Ideal Reheat Steam Cycle (10)
Consider a steam power plant operating on the ideal reheat Rankine cycle. Steam enters the high-pressure turbine at PH MPa and TH °C and is condensed in the condenser at a pressure of PL kPa. Assume the steam is reheated to the inlet temperature of the high-pressure turbine, and that pump work is NOT negligible. If the moisture content of the steam at the exit of the low-pressure turbine is not to exceed w% percent, determine:
(a) the pressure at which the steam should be reheated and show how you got the quality,
(b) the total turbine work ,
(c) the net work ,
(d) the total heat input , and
(e) the thermal efficiency of the cycle .
PH = 20 MPa, TH = 700 °C, PL = 10 kPa and w% = 12.9%.
