. A vessel of volume 0.2m3contains air at 1bar and 15oC.If 0.2 of air is pumped into the vessel, calculatethe new pressure when the vessel returned to its initial temperature. The air molar mass is 29kg/kmol and it may be assumed to be perfect gas.
Air is compressed from 1 atm to 6 atm, resulting to a temperature increase in the amount of 100 deg C from initial temperature of 25 deg C and volume of 20 liter. How much volume in liters would it occupy after compression?
Note that air can be safely assumed as an ideal gas.
Air with initial state at 12500 ft is allowed to expand isentropically to a state where pressure is 1100 psf. Calculate the specific weight after the expansion.
