Consider an ideal steam regenerative cycle in which steam enters the turbine at 3.0 MPa, 400°C, and exhausts to the condenser at 10 kPa. Steam is extracted from the turbine at 0.8 MPa to an open feedwater heater. The feed water leaves the heater as saturated liquid. The appropriate pumps are used for 2 the water leaving the condenser and the feed-water heater. Calculate (a) the thermal efficiency of the cycle, (b) the net work per kilogram of steam, and...

Question 3 [30 marks] A reheat Rankine cycle is designed for a steam power plant. Steam enters both the high- and low- pressure turbines at 600oC. The maximum and minimum pressures of the cycle are 20 MPa and 20 kPa, respectively. Steam leaves the condenser as a saturated liquid. The moisture content of the steam at the exit of the low-pressure turbine is 4% if the actual expansion process is adiabatic; 8.5% if the ideal expansion process is isentropic. The...

b) A steam regenerative cycle, shown below, is delivering 100 MW of power. Steam from the boiler is supplied to the turbine at 8 MPa, 400°C. After expanding isentropically in the 1st stage turbine to a pressure of 1 MPa, steam is taken to the reheater where its temperature is raised back to 400°C and supplied to the 2nd stage turbine. Expansion in the 2nd stage turbine is also isentropic to a pressure of 400 kPa, where a fraction (y...

3. In a reheat cycle, steam leaves the boiler and enters the high-pressure turbine (HPT) at 6 MPa and 440 °C. After expansion in the high-pressure turbine to 500 kPa, the steam is reheated to 480 °C and then expanded in the low-pressure turbine (LPT) to 10 kPa. The end states of both the HPT and LPT fall in the liquid-vapor mixture region. Draw the cycle diagram and the T-s diagram, and determine the work done to the pump, total...
