Water is the working fluid in a regenerative Rankine cycle. The pressure and temperature at the turbine inlet are 8MPa and 550?C, respectively, and the condenser pressure is 7.5KPa. The mass flow rate of steam entering the turbine is 176kg/s. Included in the cycle is one closed feed water heater using extracted steam at 1800KPa and one open feed water heater operating at 275KPa. Saturated liquid condensate is throttled from the closed feed water heater at 1800KPa to the open feed water heater. The feed water leaves the closed heater at 8MPa, 200?C, and saturated liquid leaves the open heater at 275KPa. The cooling water experiences a temperature increase from 15?C to 27?C with negligible pressure drop as it passes through the condenser. Draw the T-s diagram it would help to begin with a schematic of the cycle) and Determine: a. The net power developed in KW b. The thermal efficiency of the cycle c. The mass flow rate of cooling water in kg/s.
