A mixing chamber receives 5 kg/min ammonia as saturated liquid at 20C from one line and ammonia
Question:
A mixing chamber receives 5 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 325 kJ/min energy as heat transferred from a 40◦C reservoir, as shown in Fig. P7.94. 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?
