A steam power plant operates in a practical Rankine cycle with a steam flow rate of 65 kg/s. The steam enters the turbine at 8MPa, and discharges to the condenser at 20kPa, where the quality of the steam is 97%. The turbine power and heat loss ratings are evaluated to 70.7MW and 1MW, respectively. The pump isentropic efficiency is 80%. Determine: (a) The turbine isentropic efficiency (b) The cycle thermal efficiency (c) The rate of heat supply in the boiler, and the cycle power rating (d) The maximum possible cycle efficiency under the same conditions
