Water is the working fluid in an ideal Rankine cycle. Steam enters the turbine at 1400 lb/in² and 1000°F. The condenser pressure is 2 lb-/in.² The net power output of the cycle is 250 MW. Cooling water experiences a temperature increase from 60°F to 76°F, with negligible pressure drop, as it passes through the condenser. Step 1 Determine the mass flow rate of steam, in lb/h. m = 1536198.045 Hint Step 2 Qin Your answer is correct. Determine the rate of heat transfer, in Btu/h, to the working fluid passing through the steam generator. Hint Step 3 Your answer is correct. n = lb/h 2144195010 Btu/h Determine the thermal efficiency of the cycle. % Attempts: 3 of 4 used Attempts: 1 of 4 used
