Water is the working fluid in a regenerative Rankine cycle with one open feedwater heater. Steam enters the turbine at 1800 lb/in² and 1200°F and expands to 120 lb/in.2, where some of the steam is extracted and diverted to the open feedwater heater operating at 120 lb/in.2 The remaining steam expands through the second-stage turbine to the condenser pressure of 2 lb/in.2 Each turbine stage and both pumps have isentropic efficiencies of 85%. Flow through the condenser, open feedwater heater, and steam generator is at constant pressure. Saturated liquid exits the open feedwater heater at 120 lb/in. The mass flow rate of steam entering the first stage of the turbine is 2.30x106 lb/h. Step 1 Determine the net power output of the cycle, in Btu/hr.

In a reheat-regenerative Rankine cycle, the condenser pressure is 20 KPa. Steam enters the high pressure turbine at 5 MPa and 600 C. The isentropic efficiency of the pump is 91 % while the isentropic efficiency of the turbine is 87 %. Steam is reheated at 1.2 MPa and 500 C. For the regeneration, steam is extracted at 500 kPa for a closed feed water heater (CFWH) where the liquid exiting is throttled. Assume that the exits of the CFWH have the same temperature. Draw the schematic and T-S diagrams. Label the points by setting point 1 after the condenser, point 2 after the 1st pump, point 3 after the CFWH (horizontal exit), point 4 after the boiler, point 5 before the reheater, point 6 after the reheater, point 7 for the extraction of steam for CFWH, point 8 before the condenser, point 9 after the CFWH (vertical exit) and point 10 after throttling. Label the mass extracted for the CFWH as m1. For the actual enthalpies (due to isentropic efficiencies), use labels such as h2', h5', h7' and…
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…
