Have you ever heard the myth that a penny dropped off the empire state building can be dangerous? the penny would be traveling very quickly. Do you think this is possible?

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false
