Textbook Question

Chapter 10.9, Problem 22P

A simple Rankine cycle uses water as the working fluid. The boiler operates at 6000 kPa and the condenser at 50 kPa. At the entrance to the turbine, the temperature is 450°C. The isentropic efficiency of the turbine is 94 percent, pressure and pump losses are negligible, and the water leaving the condenser is subcooled by 6.3°C. The boiler is sized for a mass flow rate of 20 kg/s. Determine the rate at which heat is added in the boiler, the power required to operate the pumps, the net power produced by the cycle, and the thermal efficiency.

Q2: (15 Marks) A water-LiBr vapor absorption system incorporates a heat exchanger as shown in the figure. The temperatures of the evaporator, the absorber, the condenser, and the generator are 10°C, 25°C, 40°C, and 100°C respectively. The strong liquid leaving the pump is heated to 50°C in the heat exchanger. The refrigerant flow rate through the condenser is 0.12 kg/s. Calculate (i) the heat rejected in the absorber, and (ii) the COP of the cycle.
