Determine the amount of air added to the tank


A rigid tank contains 20 lbm of air at 20 psia and 70°F. More air is added to the tank until the pressure and temperature rise to 35 psia and 90°F, respectively. Determine the amount of air added to the tank. The gas constant of air is R = 0.3704 psia⋅ft3/lbm⋅R.
