An initially evacuated tank is to be filled with CO2 gas from a supply line which contains CO2 at 150 psia and 70oF. The tank volume is 10 gal, and the tank is to be filled until the pressure inside the tank is 120 psia. Determine the amount of heat transfer required if the temperature of the CO2 in the tank is to be 80oF.
State i: Inlet (Supply Line); State 1: Initial State; State 2: Final State Given: CO2; Ti = 70oF; Pi = 150 psia; V = 10 gal = 1.34 ft3; P2 = 120 psia; T2 = 80oF Assume: P1 = 0; m1 = 0 (initially evacuated). Also, as no information is given and these terms are unlikely to be significant, W = 0, and kinetic and potential energy can be neglected. No flow out of the tank. CO2 is an ideal gas with variable specific heats.
