a steam power plant operates on an ideal rankine cycle between the pressure limits of 20 mpa and 20 kpa. The mass flow rate of steam through the cycle is 12 kg/s. Steam enters both stages of the turbine at 600c. Assuming expansion to be isentropic and negligible pump work, find, (a) dryness fraction at the end of expansion, (b) the total rate of heat input in the boiler, (c) total rate of heat rejection, (d) the total work output of the cycle, (e) the thermal efficiency of the cycle.
