A rigid tank whose volume is 05 m3 initially containing, Ask an Expert

Academics

A rigid tank whose volume is 0.5 m³, initially containing ammonia at 20^oC, 1.5 bar, is connected by a valve to a large supply line carrying ammonia at 12 bar, 60oC. The valve is opened only as long as required to fill the tank with additional ammonia, bringing the total mass of ammounia in the tank to 143.36 kg. Finally, the tank holds two-phase liquid-vapor micture at 20oC. Determine the heat transfer between the tank contents and the surroundings, in kJ, ignoring kinetic and potential energy effects.
