MECHANICAL ENGINEERING JOB INTERVIEW QUESTIONS:-
1.). What is anisotropy ?
Ans: The phenomenon of different properties in different directions is called anisotropy.
2.)What is vapour pressure and when it becomes important ?
Ans: Vapour pressure is the partial pressure created by the vapour molecules when evaporation takes place within an enclosed space. It becomes important when negative
pressures are involved.
3.)Explain absolute viscosity ?
Ans: It is the ratio of shear stress and the gradient of velocity with distance between a fixed plate and moving plate (Its unit is Pa . s).
4.)What do you understand by acoustic velocity ?
Ans: Acoustic velocity is the speed of a small pressure (sound) wave in a fluid.
