40°C 4. A mixing chamber receives 5 kg/min of ammonia as saturated liquid at -20°C from one line (1) and ammonia at 40°C, 250 kPa from another line (2). The chamber also receives 325 kJ/min of energy as heat transferred from a 40°C reservoir as shown in figure. At the outlet, ammonia leaves as saturated vapor at -20°C. Find the mass flow rate in second line and calculate the total entropy generation in the process. Is this process possible?
