Moist air is at 30.0°cdb, 45.0 percent relative humidity, and 1.00 atm. determine the following: (a)partial pressure of air and water vapor (b)mole fraction of air and water (c)dewpoint temperature (d)humidity ratio (e)specific enthalpy

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.

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false
