A cylindrical pressure tank has internal dimensions of 14.0 inches diameter, and 36 inches length from end to end. Max. recommended pressure at 70degF is 200 PSI. The cylinder has a safety relief valve which is set at 250 PSI. Determine the following:
1) Inside volume of the pressure tank in ft^3
2) Specific volume of the tank at 70degF and 200 PSI
3) The mass of the air in the tank
4) The tank pressure if 3.5 lbm of air is inserted into the tank at 70degF
