A rigid tank contains 20 lbm of air at 5.3 psig and 70°F. More air is added to the tank until the pressure and temperature rise to 20.3 psig and 90°F, respectively. Determine the (a) volume, in ft and (b) amount of air added to the tank, in Ibm. The specific gas constant of air and the barometric pressure is 0.3704 psia-ft/lbm-R and 14.7 psi, respectively.

Question
A rigid tank contains 20 lbm of air at 5.3 psig and 70°F. More air is added to the tank until the pressure and temperature rise to 20.3 psig and 90°F, respectively. Determine the (a) volume, in ft³ and (b) amount of air added to the tank, in Ibm. The specific gas constant of air and the barometric pressure is 0.3704 psia-ft³/lbm-R and 14.7 psi, respectively.
