Water is the working fluid in an ideal Rankine cycle. The pressure and temperature at the exit of the steam generator is 9 MPa and 480oC. A throttle valve placed between the steam generator and the turbine reduces the turbine inlet pressure to 7 MPa. The condenser pressure is 7 kPa, and the mass flow rate of the steam is 170 kg/s. The turbine and the pump have an isentropic efficiency of 90% each. Determine
(b) The heat transfer to the steam passing through the boiler and
(a) The net power developed,
(c) The thermal efficiency (ηth).
