For the cycle in the Question
1, determine: (a) The second law
efficiency of the pump.
(b)The second law
efficiency of the closed
feedwater heater.
Q1) The reheat-regenerative Rankine cycle as shown in the figure below has a net power output of 330 MW, where the turbines operate isentropically and the pump efficiency is 85%. Assume no loss in pressure in the cycle, Additional information is given on the figure. Sketch a T-s diagram for the cycle. Determine: (a) the cycle thermal efficiency. (b) the mass flow rate into the first turbine stage, in kg/s. Steam General be 10 MPa 140°C (1) w (15 marks) Closed Feedwater Heater (b)The second law efficiency of the closed feedwater heater. 500 CO 1 MPa Q2) For the cycle in the Question 1, determine:(a) The second law efficiency of the pump.
