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?

Let's assume that we generate electrical energy by means of a turbine generator. Before the steam enters a reversible adiabatic turbine, it must be raised to 10000 kPa pressure and 450 ºC. As the steam leaves the turbine, its pressure drops to 150 kPa and a temperature of 100 C. The flow of steam in the turbine is 57 kg / s. In the meantime, your ambient temperature was measured as 25 ºC and pressure as 100 kPa. Considering these conditions, how much exergy does the steam have when entering and leaving the turbine? How much power does the turbine generate? How much power can be produced from this turbine and what is the second-law efficiency of this turbine? Calculate.
