A tank of 50 cubic feet contains saturated ammonia at 100 F and a quality of 50%. Vapor is withdrawn from the top of the tank until the temperature is 50F. The process is adiabatic.
Find:
a)The initial specific internal energy (Btu/lbm)
b)The initial mass (lbm)
c)The average enthalpy of withdrawn vapor (Btu/lbm)
d)The final quality (%)
e)The mass of ammonia that is withdrawn (lbm)
