Water is the working fluid in a rankine cycle. superheated vapor enters the turbine at 10 mpa, 4808c, and the condenser pressure is 6 kpa. the turbine and pump have isentropic efficiencies of 80 and 70%, respectively. determine for the cycle (a) the heat transfer to the working fluid passing through the steam generator, in kj per kg of steam flowing. (b) the thermal efficiency. (c) the heat transfer from the working fluid passing through the condenser to the cooling water, in kj per kg of steam flowing.
