A Rankine cycle is executed with steam expanding initially from 20 MPaa and 100 deg SH. Condensation occurs at T = 86.49 degree Celsius. All expansion and compression efficiencies are 90 %. Sketch the equipment layout and the TS diagram. Answer the following for (m = 10 + SN/10 ) kg/sec of steam circulated and fill up the blanks in the items below: 1. TS diagram with the cycle showing correct location of points with respect to saturation dome line with ne and nc = 90%. 2. If the generator efficiency = 95%, brake engine efficiency = 90% what is the brake work in KW? Answer: 3. Actual Steam Rate for the engine in Kg/KW-hr with efficiency values at item 2. Answer:
