A Rankine cycle is executed with steam expanding initially from 20 MPaa and 100 deg SH. Condensation occurs at 300 mm HG vac. All expansion and compression efficiencies are 90 %. Sketch the equipment layout and the TS diagram. Answer the following for 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. Ideal heat rate in KJ/KW-hr Answer: 3. Heat rejected at the condenser in KW (Actual) Answer: Actual Rankine engine efficiency % Answer: 5. Ideal Rankine cycle efficiency % Answer: 6. Actual Rankine cycle efficiency using pump and turbine work % Answer: 7. If the generator efficiency = 95%, brake engine efficiency = 90% what is the combined work in KW? 4. Answer: 8. If Cp water = 4.187 KJ/kg-K; cooling water enters the condenser at 12 deg C and leaves at 21 deg C, find amount of cooling water needed by the condenser in kg/sec. (ACTUAL) Answer: 9. Torque at the dynamometer if the engine is running at 900 rpm. Answer: 10. Combined Steam rate Answer
