002 Supplementary Exam (1 tempt.php?attempt3176481&page=3 A simple Rankine cycle operates between the pressure limits of 20 kPa and 3.5 MPa, with a turbine inlet temperature of 450°C. If the isentropic efficiency of the turbine is 95 percent, the turbine work output is Lütfen birini seçin: a. 864 kJ/kg b. 994 kJ/kg c. 790 kJ/kg d. 978 kJ/kg e. 737 kJ/kg The compression ratio of an ideal Otto cycle is 9. At the beginning of the compression process, the air is at 100 kPa and 15°C. The temperature at the end of the heat-addition process is 1820°C. Under cold-air-standard conditions (R=0.287 kJ/kgK, Cv=0.718 kJ/kg K, Cp%=1.005 kJ/kg K), the heat transferred from the air during the heat-rejection process is Lütfen birini seçin: a. 356.4 kJ/kg b. 417.2 kJ/kg C. 437.5 kJ/kg d. 369.3 kJ/kg
