A concentrated solar power plant receives the energy from molten salt coming in at 560◦C and leaving at 300◦C in a counter flow heat exchanger where thewater comes in at 3MPa, 60◦Cand leaves at 450◦C, 3 MPa. The molten salt has 5 kg/s flow with C_p = 1.5 kJ/kg K. What is the possible water flow rate, the rate of energy transfer, and the rate of entropy generation?
