An ideal regenerative Rankine power cycle is shown in Fig. 8.38. Steam leaves the boiler at 15

Question:

An ideal regenerative Rankine power cycle is shown in Fig. 8.38. Steam leaves the boiler at 15 MPa and 600°C with a mass flow rate of 10 kg/s. Steam is removed from the turbine at 1.6 MPa and directed to a closed feedwater heater. The remaining steam leaves the turbine at 10 kPa. Sketch the cycle on a T-s diagram and calculate:
i) The heat flow rate into the steam generator
ii) The mass flow rate diverted to the feedwater heater
iii) The net power output of the turbine
iv) The cycle efficiency
