PROJECT #4 A mixing chamber receives 5 kg/min ammonia as saturated liquid at -20C from one line and ammonia at 40C, 250 kPa from another line through a valve. The chamber also receives 325 kJ/min energy (305energy345kJ/min, increment 10 kJ/min) as heat transferred from a 40C reservoir, as shown in Fig.. This should produce saturated ammonia vapor at -20C in the exit line. What is the total entropy generation in the process? Plot the variation of the total entropy generation with changing energy and discuss the result. 1 2 H X 40C PROJECT #4 A mixing chamber receives 5 kg/min ammonia as saturated liquid at -20C from one line and ammonia at 40C, 250 kPa from another line through a valve.
