In an ideal reheat-regenerative cycle, steam enters the turbine at 8.1356Mpa and 400.356oC. After expansion to 280.356oC the steam is withdrawn and reheated to 340oC. Extractions for feedwater heating occur at 1.6356Mpa and 0.70356Mpa and condenser pressure is 0.005356 Mpa.

An ideal Rankine cycle operates between the pressure limits of 15 MPa in the boiler and 50 kPa in the condenser. The boiler generates steam at a mass flow rate of 50 kg/ s and it enters the turbine at a temperature of 1100°C. a) Calculate the net power output of the cycle, b) Calculate the thermal efficiency of the cycle.

An Actual Rankine cycle operates on a boiler and condenser pressure of 2MPa and 20kPa respectively. Steam leaves the boiler at 500C. Steam flows at a rate of 10kg/s in the cycle. The Turbine and Pump Efficiency are provided to be 87% and 89% respectively. a.) Determine the Heat Added to the boiler (kJ/s) b.) Determine the Work done by the pump (kJ/kg) c.)  Determine the Thermal Efficiency of the Cycle (%) ROUND OFF ANSWER TO SIX SIGNIFICANT FIGURES PLS USE THE GIVEN VALUES THAT IS HIGHLIGHTED IN THE IMAGE OF THE STEAM TABLE AND SUPERHEATED TABLE PLSS USE THIS VALUES
