Apower plant operates on a regenerative vapor power cycle with one open feedwater heater. steam enters the first turbine stage at 12 mpa, 560°c and expands to 1 mpa, where some of the steam is extracted and diverted to the open feedwater heater operating at 1 mpa. the remaining steam expands through the second turbine stage to the condenser pressure of 28 kpa. saturated liquid exits the open feedwater heater at 1 mpa. the net power output for the cycle is 100 mw. for isentropic processes in the turbines and pumps, determine: (a) the percent cycle thermal efficiency. (b) the mass flow rate into the first turbine stage, in kg/s. (c) the rate of entropy production in the open feedwater heater, in kw/k.
