Mechanical Engineering Interview Questions

1) What is cooling tower?

A cooling tower is a heat rejection device that rejects waste heat to the atmosphere through the cooling of a water stream to a lower temperature.

2) List different types of loads?

3) What is valve?

A valve is a device or natural object that regulates, directs or controls the flow of a fluid by opening, closing, or partially obstructing various passageways.

4) What is a nozzle?

A nozzle is a device designed to control the direction or characteristics of a fluid flow (especially to increase velocity) as it exits (or enters) an enclosed chamber or pipe. A nozzle is often a pipe or tube of varying cross-sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas).

5) What is the expression of a polytropic process?

6) What is enthalpy?

7) Explain what is isometric drawing?

8) What is caustic embrittlement?

9) What is shear force in fluid particle?

10) What is gutter and where it is used?

11) What is difference between fan and blowers?

12) What is Auto Dosing?

13) What amount of heat energy loss in ESP?

14) Explain the function of the strainer in IC engine?

15) What is difference between enthalpy & entropy?

16) What is flange rating?

17) What is vapour Lock?

18) What is moisture choking?

19) What is Deriaz turbine?

20) What is Navier-stroke equation.

21) What is quazi-crystal?

Quasicrystal, also called quasi-periodic crystal is a matter formed atomically in a manner somewhere between the amorphous solids of glasses (special forms of metals and other minerals, as well as common glass) and the precise pattern of crystals. A quasicrystal is a structure that is ordered but not periodic.

22) What is Recuperator & Regenerators?

23) What is slip ratio in thermal power plant?

24) What is boiler mounting?

25) What is fast breeder reactor?

26) What are the anti friction bearings?

27) What is damping ratio?

28) Where diamond pin locator is used?

29) Which process used for cutting thicker plates?

30) Explain von mises stresses.

31) What is 6 stroke engine?

32) What is the difference between fuel NOx and thermal NOx ?

33) What is radiosity?

34) What is microbial desulphurisation?

35) How to calculate the turbine efficiency?

Turbine efficiency is the ratio of actual work output of the turbine to the net input energy supplied in the form of fuel.
