Water is the working fluid in a rankine cycle. superheated vapor enters the turbine at 8 mpa, 5608c with a mass flow rate of 7.8 kg/s and exits at 8 kpa. saturated liquid enters the pump at 8 kpa. the isentropic turbine efficiency is 88%, and the isentropic pump efficiency is 82%. cooling water enters the condenser at 188c and exits at 368c with no significant change in pressure. determine (a) the net power developed, in kw. (b) the thermal efficiency. (c) the mass flow rate of cooling water, in kg/s.
