Steam is the working fluid in an ideal Rankine cycle. Saturated vapor enters the turbine at 10MPa and saturated liquid exits the condenser at a pressure of 7.5kPa. The net power output of the cycle is 120MW. Determine for the cycle (a) the thermal efficiency, (b) the back work ratio, (c) the mass flow rate of the steam, in kg/h, (d) the rate of heat transfer, Qin, into the working fluid as it passes through the boiler, (e) the rate of heat transfer, Qout, from the condensing steam as it passes through the condenser, (f) the mass flow rate of the condenser cooling water, in kg/h, if cooling water enters the condenser at 15C and exits at 35C. Ans: (a) 38%, (b) 1.0%, (c) 124kg/h, (d) 316MW, (e) 196MW, (f) 2439kg/s
