Water is the working fluid in a rankine cycle. steam enters the turbine at 150 kpa and 200°c. the condenser pressure is 20 kpa. both the turbine and pump have isentropic efficiencies of 80%. the working fluid has a negligible pressure drop in passing through the boiler. the net power output is 1×109 w. the cooling water experiences a temperature increase from 20°c to 35°c with negligible pressure drop as it passes through the condenser. determine for the cycle: (a) the mass flow rate of steam in [kg/hr (b) the rate of heat transfer in [kj/hr] to the working fluid passing through the steam generator (c) the thermal efficiency (d) the mass flow rate of cooling water in [kg/hr] answer) (a) 12805e7 kg/hr; (b) 3.3567e 10 kj/hr; (c) 10.7%; (d) 4.777& e8 kg/hr turbine 慚 cooling water pump condenser wi
