Extracted text: 2. The turbine of a 1-MW steam power plant is supplied with superheated steam at 3000 kPa and 573 K, where it is expanded to the condenser pressure of 5 kPa. The isentropic efficiency of the turbine is 85%. The saturated liquid leaving the condenser is pumped to the boiler pressure by means of the feed water pump, the thermodynamic efficiency of which is 80%. Determine: (a) The efficiency of the ideal Rankine cycle (b) Thermal efficiency of the cycle (c) The rate of production of steam.
