1. The compressed air tank has a volume of 0.6 m. The temperature is 15°C and the atmospheric pressure is 101.35 kPa. When the tank is filled with air at a gage pressure of 244.74 kPa, determine the density of the air and the weight of air in the tank. Hint: Ideal gas law should be used. R-28 m/sK

A vertical hydraulic cylinder has a piston with a diameter of 115 mm.If the ambient pressure is 100 kPa,determine the mass of the piston if the pressure inside is  950 kPa.

Determine the mass of air in Ibm when the pressure is 19.99 psi and the temperature is 85.1°F in a closed chamber with dimensions 30.5 ft x 15.5 ft x 15.8 ft. Assume air to be an ideal gas. N

An air bubble rises from the bottom of the well where the temperature is 20 degrees celsius to the surface where the temperature is 50 degrees celsius. If the existing pressure at the surface of the well water is 101.3 kPa and the pressure in the bottom of the well is 200 kPa, determine the percent increase in the volume of the bubble.
