A steam power plant operating on a regenerative cycle, as illustrated in Fig. 8.5, includes two feedwater heaters. Steam enters the turbine at 6500 kPa and 873.15 K (600°C) and exhausts at 20 kPa. Steam for the feedwater heaters is extracted from the turbine at pressures such that the feedwater is heated to 463.15 K (190°C) in two equal increments of temperature rise, with 5 K (5°C) approaches to the steam-condensation temperature in each feedwater heater. If the turbine and pump efficiencies are both 0.80, what is the thermal efficiency of the cycle and what fraction of the steam entering the turbine is extracted for each feedwater heater?
