In a reheat-regenerative Rankine cycle, the condenser pressure is 10 KPa. Steam enters the first turbine at 12.5 MPa and 500 oC. Steam is reheated at 3 MPa at the same temperature before entering the second turbine. For the regeneration, steam is extracted from the second turbine at 0.5 MPa to an open feedwater heater (OFWH). Draw the schematic and T-S diagrams. Label the points by setting point 1 at the condenser outlet, point 2 at the 1st pump (right after the condenser) outlet, point 3 at the OFWH outlet, point 4 at the 2nd pump outlet, point 5 at the boiler outlet, point 6 at the reheater inlet, point 7 at the reheater outlet, point 8 for the extraction of steam to OFWH and point 9 at the condenser inlet. Use 2 decimal places for the enthalpy, steam quality (%), thermal efficiency (%), and other energies. For the fraction of steam (y) and entropy (s), use 4 decimal places. For the specific volume, use 6 decimal places. USE THE STEAM TABLES FROM CENGEL'S BOOK ONLY 1.T-S Diagram 2…
