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.
