1. Consider a steam power plant which works on the actual Rankine cycle. The steam leaves the boilers at 10 MPa and leaves at 500 °C and enters the steam at lower pressure and temperature i.e. 9.5 MPa and 450 °C, respectively than the steam leaves the boilers because of the losses due to heat transfer and frictional effects in connecting pipe. The pressure at the exit of the turbine is 10 kPa, and the turbine operates adiabatically. Liquid leaves the condenser at 8 kPa, 35 °C. The pressure is increased to 10.5 MPa across the pump. The turbine and pump isentropic efficiencies are 90%. The mass flow rate of steam is 80 kg/s. Determine (a) thermal efficiency (b) heat loss from connecting pipe between boiler and turbine, in kW.
