Calculate the specific volume of an air-vapor mixture in cubic meters per kilogram of dry air when the following conditions prevail: t= 20°C, W = 0.0015 kgv/kgda, and pt = 80 kaa.

The air in an automobile tire with a volume of 1.23 ft3 is at 72°F and 0.5 bar. Determine the amount of air that must be added to raise the pressure to the recommended value of 1 bar Assume the atmospheric to be 14.7 psia and the temperature and the volume to remain constant.

A 2.8 m^3 rigid tank is filled with saturated liquid vapor mixture of water at 300C. If 2% of its volume is liquid and the rest is vapor, the total mass in the tank in kg is?

A piston-cylinder device initially contains 10L of liquid water at 25C and at atmospheric pressure of 101.325 kPa. Heat is added at constant pressure until the entire liquid is vaporized. (a) what is the mass of water (b) final temperature (c) amount of heat absorbed by the water.
