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. For more interview questions join Mechanical Engineers Rocks.
