Freon-12 is contained in a 1 ft^3 tank as indicated in Fig2. The tank is intiaaly contians 90% liquid and 10% vapor, by volume, at 80F. The valve is then opened and Freon-12 vapor flows out, leaving the nozzle at 15 lbf/in^2, with a velocity of 700ft/s.During this pocess heat is transferred to the tank such that Freon-12 inside remains at 80F. Deremine a) the total mass exhausted when the tank contains saturated vapor. b) The total heat transferred to the tanks during this process
