11. You Can See, We Have Compression Station At Different Location, Why Don’t We Use Pump Station?

We are dealing with the conveying of the gases. Compressors are meant for conveying of gases while pumps deal with liquids. Hence, we have compression stations.

12. What Is Difference Between Reciprocating Compressor And Rotating Compressor?

In reciprocating compressor the energy transfer is due to the volume changes while in rotating compressor energy transfer is due to dynamic action (velocity). Also, reciprocating compressor are meant for high head and also does not have continued mass flow rate whereas rotating compressor are meant for low head and high mass flow rate.

13. Do You Know Rankine Cycle? What Are The Four Components In It And The Purpose Of Each?

• Pump – Work input.
• Boiler- Heat addition.
• Turbine- Work output.
• Condenser- Heat rejection.

14. Why Don’t We Use Compressor And Send It To Boiler?

The work input for the compressor is more as compared to pump. So the net work output is less in case of compressor.

15. What Is The Property Of Fluid That Is The Cause For More Work Input In Compressor Than In Pumps?

Bulk density.  The density of gas is low and hence has high specific volume than liquid. So, we require handling more volume. Also gases are more susceptible to expansion and the gases are moving in adverse pressure gradient. So we require more work input.

16. Which Is Your Dream Company? Why?

GAIL, because here I will get an opportunity to learn latest technology and machines. Also it is a budding company and I will get to explore a lot by working in different domains.

17. Which Domain Do You Prefer?

I prefer maintenance for my initial duration of my job and then will prefer operation and maintenance or design. Since maintenance will get me to acquire knowledge of the different equipment residing in the plant and also help to get familiar with process flow. So it helps in designing of new plant.

Also, I would like to work where the company thinks I suits best and will give my best for the benefit of company.

18. What You Have Done In Training? ( I Did My Second Year Training In Gail).

Then, I said about the breakdown maintenance of centrifugal pumps, learn hot tapping, heat exchanger, and extruder.

19. What Is Hot Tapping?

It is to give a new pipeline in a charged line.

20. How Is C2+ Separated From Natural Gas?

There is unit GPU unit, in which there is a demethanizer column (fractional distillation) which separates methane from natural gas and we get C2+. Then they asked is it heating process or cooling. It is a cooling process since temperature goes upto -180 C. Then he refined it so it is a chilling process.

21. Who Is More Imps: Team Or You? Why?

Team, because if team succeed I will also get appreciation and prospers.

22. What Is Most Important For A Team To Get Success?

Communication- easy flow of information among people and cooperation. If there is no communication, it will be very difficult to take wise and good decisions.

23. Define Entropy?

It is measure of randomness. Then they say to give an example from general life.(This can be understandable by a general person). Then I said, if we have a group of people closed in a park then suddenly some minister or actress comes, there will be a lot of excitation and “shor gulla and people will rush to see them. So, in this randomness increases and hence entropy increases.

24. What Is The Difference Between Impulse Turbine And Reaction Turbine?

In impulse turbine, pressure changes take place outside the rotor. Hence degree of reaction is zero whereas in reaction turbine pressure changes in rotor only. Hence degree of reaction is one.

25. Tell Me One Thing, In India, 40% People Are Below The Poverty Line Also We Are Investing In Aerospace Programs. Is It Justified According To You?

We have different schemes for the betterment of poor people like Rajiv Gandhi scheme, Indira Gandhi scheme. And we are working on them. But at the same time, we have to stand globally so we require investing in aerospace programs. Then he said you have not given the answer of my question “Is it justified”. Yes sir, It is justified as it will help in increasing employment and attract foreign investment which can be used for the poor people.

26. Are You Willing To Work Anywhere In India? Is There Any Problem?

There is absolutely (more sophisticated word can be used here. absolutely sounds some weird. Since there is no absolute satisfaction) no problem.
