Figure 8.37 shows an ideal Rankine power cycle with regeneration and reheat. Steam leaves the boiler at 8 MPa and 600°C with a mass flow rate of 20 kg/s. Some steam is removed from the high-pressure turbine at 500 kPa and sent to an open feedwater heater. The remaining steam flow leaves the high-pressure turbine at 200 kPa, where it is reheated to 500°C and sent to the low-pressure turbine. The steam then leaves the low-pressure turbine at 20 kPa. Sketch this cycle on a T-s diagram and determine:
i) The steam flux extracted to go to the feed-water heater
ii) The total heat addition by the boiler
iii) The power output of the turbine
iv) The quality, or temperature, of the steam leaving the turbine
v) The heat loss from the condenser
vi) The total horsepower of the two pumps
vii) The thermodynamic efficiency of the cycle
