Help A mixing chamber receives 6 kg/min ammonia as saturated liquid at -20°C from one line and ammonia at 40°C, 250 kPa from another line through a valve. The chamber also receives 327 kJ/min energy as heat transferred from a 40°C reservoir. This should produce saturated ammonia vapor at -20°C in the exit line. What is the mass flow rate in the second line, and what is the total entropy generation in the process?
