Qin Hint 1715890000 Btu/h Step 3 Determine the thermal efficiency of the cycle. = i Save for Later % Attempts: 1 of 3 used Attempts: 1 of 3 used Attempts: 0 of 3 used Submit Answer Water is the working fluid in a Rankine cycle. Steam exits the steam generator at 1500 lbf/in. and 1100F. Due to heat transfer and frictional effects in the line connecting the steam generator and turbine, the pressure and temperature at the turbine inlet are reduced to 1400 lbf/in.2 and 1000F, respectively. Both the turbine and pump have isentropic efficiencies of 90%. Pressure at the condenser inlet is 2 lbf/in., but due to frictional effects the condensate exits the condenser at a pressure of 1.5 lbf/in. and a temperature of 110F. The condensate is pumped to 1600 lbf/in before entering the steam generator. The net power output of the cycle is 5.5 x 10 Btu/h. Cooling water experiences a temperature increase from 60F to 76F, with negligible pressure drop, as it passes through the condenser. Determine for the cycle: (a) the mass flow rate of steam, in lb/h. (b) the rate of heat transfer, in Btu/h, to the working fluid passing through the steam generator. (c) the percent thermal efficiency. (d) the mass flow rate of cooling water, in lb/h.
