Question:

A 25-ft3 insulated, rigid tank contains air at 110 lbf/in 2, 75 F. A valve on the tank is opened, and the pressure inside quickly drops to 15 lbf/in 2, at which point the valve is closed. Assuming that the air remaining inside has undergone a reversible adiabatic expansion, calculate the mass withdrawn during the process.
