A steady-state system for producing power consist of a pump, heat exchanger and a turbine. Water steam power plant operates on an ideal reheat– regenerative Rankine cycle. Steam enters the highpressure turbine at 10 MPa and 550°C and leaves at 0.8 MPa. Some steam is extracted at this pressure to heat the feedwater in an open feedwater heater. The rest of the steam is reheated to 500°C and is expanded in the low-pressure turbine to the condenser pressure of 10 kPa. Determine the entropy generation associated with the reheating and regeneration processes. Assume a source temperature of 1800 K.  Please can you specify the assumptions in this problem?

A steam power plant operates on an ideal reheat–regenerative Rankine cycle with onereheater and two feedwater heaters, one open and one closed. Steam enters the highpressure turbine at 15 MPa and 600°C and the low pressure turbine at 1 MPa and 500°C.The condenser pressure is 5 kPa. Steam is extracted from the turbine at 0.6 MPa for theclosed feedwater heater and at 0.2 MPa for the open feedwater heater. In the closedfeedwater heater, the feedwater is heated to the condensation temperature of the extractedsteam. The extracted steam leaves the closed feedwater heater as a saturated liquid, whichis subsequently throttled to the open feedwater heater. Show the cycle on a T-s diagramwith respect to saturation lines. Determine (a) the fraction of steam extracted from theturbine for the open feedwater heater, (b) the thermal efficiency of the cycle, and (c) thenet power output for a mass flow rate of 42 kg/s through the boiler.

1. A steam power plant operates on a reheat regenerative Rankine cycle with a closed feedwater heater. Steam enters the turbine at 9 Mpaa and 500 deg C at a rate of 15 kg/sec and is condensed in the condenser at a pressure of 20 kPaa. Steam is reheated at 3 MPaa, 500 deg C. Some steam is extracted from the turbine at 1 Mpaa and is completely condensed in the closed feedwater heater and pumped to 9 Mpaa before it mixes with the feedwater heater at the same pressure in a mixing chamber. The Terminal Difference for the CFWH, (i.e., the difference between the temperatures of the fluids leaving the heater) is 3 deg C. Assuming an isentropic efficiency of 89 percent for both the turbines and the pumps, determine: 1. Equipment Layout and TS diagram for the cycle 2. Ideal extracted steam for feedwater heating in kg/kg 3. Actual extracted steam for feedwater heating in kg/kg4. Ideal Turbine work (KW)5. Ideal engine efficiency (%)
