The net work for a given reheat Rankine cycle is 80MW. Steam at 10 MPa and 500C enters the first turbine and then, the second turbine at 1.2 MPa and 500C. Saturated liquid exits the condenser at 20 kPa. Draw the schematic and T-S diagrams. Label the points by setting point 1 at the condenser outlet, point 2 at the pump outlet, point 3 at the boiler outlet, point 4 at the reheater inlet, point 5 at the reheater outlet, and point 6 at the condenser inlet. Use 2 decimal places for the enthalpy and other energies in solving and for the final answers. For the steam quality (x) and entropy (s), use 4 decimal places in solving. For the specific volume, use 6 decimal places. IMPORTANT: USE THE STEAM TABLES FROM CENGEL'S BOOK ONLY (uploaded already in the files section). Determine the following: Enthalpy at point 2 in kJ/kg = Enthalpy at point 4 in kJ/kg = Enthalpy at point 5 in kJ/kg = Enthalpy at point 6 in kJ/kg = Thermal Efficiency in % = Heat added in kJ/kg = Heat rejected in kJ/kg = Work turbine in kJ/kg =
