plementary Exam (1 x php?attempt=D176481 At the beginning of the compression process of an ideal Diesel cycle, air is at 95 kPa and 25°C, and 640 kJ/kg of heat is transferred to air during the heat-addition process. At the end of isentropic expansion process, air is at 265 kPa and 607°C. Taking into account the variation of specific heats with temperature, the thermal efficiency of the cycle is Lütfen birini seçin: а. 30.4% b. 27.5% c. 41.2% d. 37.3% e. 43.7% Sonraki sayfa
The adiabatic efficiencies of the compressor and turbine used in an air-standard Brayton cycle are 85% and 90%, respectively. If the cycle operates between 14.7 and 55 psia and if the maximum and minimum temperatures are 1500 F and 80 F, respectively, compute the thermal efficiency of the cycle. Assume constant specific heats.
