Fluid Handling Systems

As a mechanical engineering graduate you must know that a key element in fluid systems is the transmitting means of power from one location to another.

Now to construct a hydraulic or pneumatic system needs a design or selection of various components, and also determine how they will interact. Most overlooked point is that the fluid, and the means of moving it from one location to another, are essential in any fluid-power system.

As the functions of hydraulic fluid are very basic; to transmit power efficiently and lubricate moving parts, with low maintenance it is often ignored. But if you use the wrong fluid, or do not maintain it properly, it could even destroy a system. As polluted air can foul the compressors, jam valves, and ruin an instrument.

In addition to fluids, the various ways that transmit fluid like hose, tubing and connectors and also the components that keep the fluid in good working condition like filters, heat exchangers, lubricators, and dryers are very essential ingredients of fluid-power systems.

Fluids

Hydrocarbons conventionally have been the main choice for hydraulic work. This remains popular where there is no fear of fire, no possibilities of, no wider temperature variations, and no environmental problems or concerns.

Fire protection might dictate choice of a nonpetroleum fluid, mainly when a broken hydraulic line could spray fluid into an ignition source. Work environment might suggest a nonhydrocarbon fluid where a hydrocarbon fluid that could spoil food-related products or pollute a river.

Hydraulic fluid must be looked for general compatibility with the system. Fluids are of five types from point of view of evaluation: premium antiwear, standard antiwear, rust and oxidation-inhibited nonantiwear, water-based, and phosphate esters.

Premium antiwear are recommended for systems that use both piston and vane equipments. The fluids allow the operation at full catalogue rating with maximum life shell.

Standard antiwear are comparatively lesser stable than the premium fluids as they contain more additives. The fluids could be used with piston pumps, but speed limit must be upto 1,800 rpm and pressure ~ 3,000 psi.

Vane equipment, on the other hand, could be used at maximum catalogue ratings with maximum life shell.

Nonantiwear, rust and oxidation-inhibited fluids are also divided into stable and less-stable types. The stable fluids, like turbine oils, are more preferable for piston equipments. The fluids permit operation at full catalogue ratings with maximum life shell.

These fluids could be used with well designed vane equipment but at lower ratings and life.

The lesser stable class of these fluids includes tractor and transmission fluids. They are most suitable for use in piston equipment at full catalogue rating, but life shell is difficult to ascertain.

Water-based fluids are invert emulsions and water glycols. Piston pumps operate well on these fluids but have certain disadvantages. For example, absolute inlet pressure must be about 25% higher than with petroleum-based fluids, and minimum inlet pressure ~13 psia.

Only specially designed vane pumps could be used with these fluids. Again, absolute inlet pressure must be 25% higher than with petroleum-based fluids, and minimum inlet pressure is 13 psia.

Phosphate esters could be used with piston and vane equipment at full catalogue ratings. But, absolute inlet pressure must be about 35% higher than hydrocarbon fluids. Viton-A seals are suitable with most phosphate esters; but, some of these fluids need EPR seals.

So now we conclude the discussion.

Why Cooling Capacity Unit Of Home Refrigerator And Air Conditioner Is different

We often wonder why the capacity of a domestic refrigerator and Air Conditioner (AC) are so different though both are refrigeration system. In this blog topic we shall discuss some of the key differences between the two.

So what is the main difference with respect to the cooling capacity?

A major difference between the two is the point of supply for the gases. Refrigerator has gases installed in a series of tubes. In old ones, the gas was CFC, but since it has harmful effects on people, so refrigerators do not contain them anymore. HFC-134a is the sole gas used as a coolant in refrigeration systems. AC systems use built-in chemicals, but also air from the room. In built gases in an air conditioning unit cools air that circulates through the unit; the unit next redistributes the cooled air in the room.

ACs have circulation systems created to project cool air away from the units while refrigeration units have circulation systems designed to retain the coolant in a confined space. Refrigerators circulate cool liquids and gases through a series of tubes and vents. Cool air from within a refrigerator is taken into a compressor that recycles the gas through the tubes. ACs, while employing tubes in the coolant system, has fans for air dispersal. Unlike refrigerators, that keep gases contained to a pre-determined space, ACs disperse cool air throughout areas of unknown volume.

The capacity of domestic refrigerator is generally rated in ‘Litre’.Thus, litre capacity indicates the volume or space to be cooled by the domestic refrigerator.

On the other hand, the AC capacity is given by the term ‘Ton of refrigeration’. Now ton is actually a name given to the amount of heat to be extracted from 1 short ton (907.18474 kg) of water at 0 degree C to convert it to the ice at the same temperature in 24 hours.

In simple words, refrigeration rate required freezing 1 ton of water to ice in 24 hours at 0 degrees C. 

Thus, 1 Ton of refrigeration = 1 TR = (latent heat of ice)x(amount of water)/time 

= 334 x 907.18474 /(24 x 3600)

= 3.50 kW

Hence it is clear that the refrigeration system has a different capacity term viz. ‘Litre’ (Space to be cooled) and ‘Ton’ (energy to be removed for cooling)

Essential software to learn in Mechanical Engineering

The software tools are used by an engineer to get things done easy and fast. In this blog topic, we mentioned below the important and essential software tools which should be learned during your bachelor course in mechanical engineering.

AutoCAD ( A fundamental CAD software for designing and draftinging purpose)

2. Pro/Engineer Complete parametric 3D CAD/CAM/CAE software)

3. C Language (Programming language)

4. ANSYS (A software for analysis or simulation.


AutoCAD

It is drafting software which requires drawing 2D objects as well as 3D modelling.

Importance

In the process of being a Mechanical engineer, one has to submit final year project which involves experimental or fabrication work or theoretical analysis. To take any project, one must use at least one software or more.

Pro Engineer 

It is a complete package of drawing, modelling and analysis. Its design package has 2D drawing, 3D models and an assembly. It also functions like 2D CAD, 3D CAD, Data exchange like IGES and other formats, Dynamics publishing, engineering calculations, Visualization and mock up etc.

C Programming Language 

If you are mechanical student, then you must know the great importance of C language as when you need to learn computational subjects, and the calculations for a number of numerical methods. There are many programming languages but C is one of best. If you use MATLAB, it will need more memory but fewer skills, FORTRAN is also competitive to C but if you know the C language, you don’t need to learn the rest and even it is required, you could learn easily as all programming languages are very similar.

ANSYS

Finite Element Method or FEA is one of the numerical methods in science that deals with approx numerical solutions of problems like structural, thermal, fluid or fluid structure interface. Generally for problems with thermal and fluid, software packages like FLUENT and GAMBIT is popular. To mention, the latest ANSYS versions include FLUENT. 

Hence, without the software, it is impossible to work or do research in the areas of Mechanical Engineering. So, be attentive in your classes during the bachelors and learn the various software tools as you need them at regular basis.

Mechanical Technical Interview Questions For Thermodynamics

In today’s blog topic we are sharing some of the mostly asked and important questions from interview point of view.

1. Why Thermodynamics is important in the field of Mechanical Engineering

As all the mechanical systems obey the rules of thermodynamics; it is very important for the mechanical engineers. 

2. State the Laws of Thermodynamics.

The three laws of thermodynamics are:

1st Law: 

Energy can neither be created nor destroyed; but can change forms. In an isolated system, the total energy always remains the same. 

Second Law: 

The entropy of the universe increases during any spontaneous process. 

Third Law:

As temperature reaches absolute zero, the entropy of a system becomes minimum. 

3. What are the Laws of energy conservation? 

Energy can neither be created nor be destroyed; but can be transformed from one form to another.

4. Is a boiler a closed system?

Yes. 

5. What is a Carnot engine?

It is an imaginary engine which follows Carnot cycle and provides 100% efficiency.

6. Difference between Gas and Vapour

  1. Vapour can change back and forth into liquid and solid states but a gas can’t.
  2. Gases cannot be seen while vapours are visible.
  3. Vapours settle on ground while gases don’t.

7. Differentiate Boiling Point and Melting Point

  1. The melting point is the temperature at which a solid changes to liquid state.
  2. The boiling point is the temperature ate which liquids transform into gas.

8.What is the effect of reheat on Rankine  cycle? 

1. Increased efficiency 

2. Increased yield

3. Both

4. None of these.

1.Increased efficiency

9. What is flashpoint?

Flash point is the lowest temperature at which vapour of a combustible liquid can be ignited in air.

10. What is refrigerant? 

A substance that transfers heat from one place to another, developing a cooling effect. Water is a refrigerant in absorption machines. 

11. What is Otto cycle. 

Designed by Nicolas Otto, an Otto cycle can be explained by a pressure volume (P/V) relationship diagram. It depicts the functioning cycle of a four stroke engine. The cycle begins with an intake stroke, closing the intake and then moves to the compression stroke, starting of combustion, power stroke, heat exchange stroke where heat is rejected and the exhaust stroke.

12. How to measure temperature in a Wet Bulb Thermometer? 

Wet bulb temperature is measured in a wet bulb thermometer by covering the bulb with a wick and soaking it with water. It corresponds to the dew point temperature and relative humidity.

13.) In a Thermal Power Plant why Deaerator (D/A) is placed on a height?

To build a very high pressure and the temperature for a boiler feed water pump and it discharges high pressure water to the boiler.

14.) What are the differences between gas turbine and a steam turbine? 

Gas turbine works on Bryton cycle whereas a steam turbine works on Rankine cycle. The making and operation of a gas turbine is entirely different to steam turbine.

15) Where does stress corrosion cracking occur in a stream turbine?

In the wet stages.

General Considerations In Designing A Machine

Today in this blog topic we shall discuss the general considerations while designing machine components.

Following are the facts you need to consider in designing a machine component:

Following are the facts you need to consider in designing a machine component:

Work facilities

Working environment plays an essential key role in designing a machine component. A designer must be familiar to workshops and work facilities. It is important to plan and supervise the workshop operations and the design methods regarding forming, forging and casting. 

Assembly

A machine comprises of parts or components and must be assembled as a unit before it is ready for function. Large units should often be assembled in the workshop and then transfered to their servicing place. The final location is significant and the designer should know the exact location and the local facilities.

Kinematics

Motion of the parts might be

(i) Rectilinear motion that is unidirectional and reciprocating.

(ii) Curvilinear motion that is oscillatory, rotary and simple harmonic.

(iii) Constant velocity and constant or variable acceleration.

Successful operations has very simple arrangement of parts which will provide the motion.

Friction

There is always loss of power owing to frictional resistance and you must remember that starting friction is higher than friction at running. To overcome this hurdle, exact lubrication is very important. Consider the matter of lubrication of all surfaces which move in contact with others, whether in rotation or sliding.

Cost of construction

Yielding and making a component must be smooth, easy and its overall cost must be minimum. So the cost of construction is an important asset to build or make a component.

Size of the parts

Form and size of the part are based on judgement. Either the part is small but it may be checked that the stresses induced in the designed cross-section are reasonably safe. To design any machine component or part for form or size, it is essential to know the forces which the part must sustain. Designer must know the suddenly applied or shock/impact load which may cause the failure.

Safety measures

Certain machines are very dangerous during operation, typically those which need speed to ensure production at a maximum rate. So safety measures must be followed to avoid accidents.

Stress and load

The load, on a machine parts might act in different ways, due to which the internal stresses are set. These stresses are like bearing, compressive, torsion , bending stresses etc.

Quantity

The number of parts or machines to be manufactured affects the design in several ways. 

Economy

In designing the features of a machine must be carefully studied. The start, control and stop levers must be located on the basis of convenience of handling. Replacement of other parts is to be located in an easy mounting positions.

Material selections

It is very important that a designer must have a thorough knowledge of the properties of material and their behaviour under working conditions. Important features of a material are its strength, durability, flexibility etc.

We conclude the discussion now.

Automobile Types: Rear Axle or Live Axle

To mention, rear axle is the last member of a power train. In most of the automobiles, real axle is the driving axle. It lies in between the driving wheels and the differential gear and transmit power from the differential to the driving wheels. It has two half shaft connected to the differential gear, one for each wheel. The inner end of each half shaft connected to the sun gear of the differential and the outer end to the wheel. The rear axle and differential gear completely encloses in a box which protects them from water, dust or any injury.

Function of a rear axle:

The rear axle does following two main functions.

  • 1. Carries weight of the vehicle.
  • 2. Rotates and transmits power from the engine to the wheels.

Classification of rear axle:

Rear axle is classified by two methods.

1. According to the making of axle:

(A.) Banjo axle:

An axle with a single shaft and a final drive assembly is carried in a separate case which is bolted to the axle box. The banjo is often used for small and light vehicles.

(B.) Split axle:

Here the shaft is used with the central house has the differential gear and it is fitted with a tube on each side to bear the half axles and bearing.

2. On the basis of the method of supporting:

(A.) Half floating rear axle:

In this axle the support of the axle, is inside the case. The axle of the wheel is at the centre of the axle case.The whole weight of the vehicle is first transmitted to the suspension spring and next to the axle case, rear axle, wheel and ground.

(B.) Three quarter floating rear axle:

In this axle bearing is on the outer side of case between the wheel and the axle case. The wheels are fitted at the end of the axle by means of a key, bolt or nut.

The weight of the vehicle is supported partially by the axle case and partially by the axle. The main benefit of this type of axle over the half floating one is that the major part of the load is taken by the axle case and not by the axle. The function od the axle is to take care of the rotating and transmits the power.

(C.) Full floating rear axle:

Here the bearing is on the outer side of case between the wheel and the axle case. The axle is not supported by the bearing at all the ends. The wheels are fitted at the end of the axle by means of a key, bolt or nut.

Thus the total weight of the vehicle is supported by the wheel and axle case. The axle has no strain caused by the weight of the vehicle on end thrust. It transfers only the driving torque.

Liquid Droplets Can Connect Two moving Parts Without Any Solid Contacts

Can you imagine liquid droplets could connect two moving parts without any solid contacts? Yup! That’s what we shall discuss today in this blog topic. Another innovative idea for your mechanical engineering project for the semesters.

Researchers in MIT (Massachusetts Institute of Technology) developed an approach to use liquid droplets to link two moving parts without any solid contacts. A breakthrough innovation which makes several things possible in the field of MEMS (Micorelectromechanical Systems).

Te mentions, MEMS are tiny machines designed for industrial uses in electronic industry like manufacturing of chips and rerlated components. As wear and failure of small machines is a big issue. Since the connections between two moving parts are very tiny in such machines they fail easily. By finding an alternative approach to such solid connections; the industry is taking a huge raise.

The applied principle in this approach is very common. It is known that certain surfaces tend to repel water while others attract. The water droplets on a hydrophobic surface tend to stay there while those on a hydrophilic surface tend to spread evenly. In case of the former, the height of a water droplet will be much larger than a droplet in the latter case. By altering this water -water repulsion or attracting qualities; the water droplets could be moved.

In case of certain dielectric surfaces the above qualities could be altered by passing small amount of electricity. Then you will get a water droplet that changes its shape and size when you change or flip a switch. To say, the concept is nothing new but the researchers had the idea to put it in for a practical application like moving a platform. They put a tiny platform on top of two water droplets and changed its height by changing the flow of electricity to the platform on which they are placed. The same method could be applied to move the droplets from one position to another or tilt them. And a simple experiment made a gateway to a new era of MEMS.

Avoiding wear and failure in MEMS machines are advantages of this experiment and also proves as a method to make precise movements. The initial experiments will help control the platform with a precision of 10 microns. This has nice scope in many industries where precise movements are needed, for instance laser related experiments.

Another advantage is that it is vibration resistant when compared to solid connections. As the experiment is very simple; we can speculate that it wouldn’t be long before when we see them in real world applications.

Hope you liked this discussion. You can look after many videos to get a practical insight for the same.
