A modified Rankine steam cycle is shown for reheating, a closed feedwater heater, and an open feedwater heater. high pressure turbine receives 100 kg/s of steam from the steam boiler. The feedwater heater output states for boiler feedwater and condensed steam are the ideal states normally assumed. The following data tables give saturation data for pressures and data for h and s at selected states. (a) Draw the T-s diagram for the ideal cycle. (b) Determine the net power output of the cycle, in MW.
