A power plant operates on a regenerative vapor power cycle with one closed feedwater heater. Steam enters the first turbine stage at 10 MPa, 500°C, and expands to 1 MPa, where some of the steam is extracted and diverted to a closed feedwater heater. Condensate, exiting the feedwater heater as saturated liquid at 1 MPa, passes through a trap into the condenser. The feedwater exits the heater at 10 MPa with a temperature of 175°C. The condenser pressure is 6 kPa. The mass flow rate (m) into the first stage turbine is 290 kg/s. Assume isentropic processes in each turbine stage and the pump. (Figure 1)
