The basic cycle for a steam power plant is shown by Fig 8.1. The turbine operates adiabatically with inlet steam at 6800 kPa and 550deg.C and the exhaust steam enters the condenser at 50deg.C with a quality of 0.96. Saturated liquid water leaves the condenser and is pumped to the boiler. Neglecting pump work and kinetic and potential energy changes, determine the thermal efficiency of the cycle and the turbine efficiency.
