Water is the working fluid in an ideal Rankine cycle. Superheated vapor enters the turbine at 8 MPa, 450 °C. The condenser pressure is 7.5 kPa. The net power output of the cycle is 100 MW.
(a) Draw and label the T-s diagram for the ideal Rankine cycle that you would use to solve this problem.
(b) Determine for the cycle the rate of heat transfer to the working fluid passing through the steam generator, in kW.
(c) Calculate the thermal efficiency.
(d) Determine the rate of heat removal at the condenser, in kW. If the cooling water enters the condenser at 15 °C and exits at 35 °C (with negligible pressure change) what would be the required mass flow rate of the condenser cooling water in kg/h?
