For the same heat input and compression ratio, the most efficient cycle is
An air-standard Diesel cycle consists of the following processes:1-2: Air is compressed isentropically.2-3: Heat is added at constant pressure.3-4: Air expands isentropically to the original volume.4-1: Heat is rejected at constant volume.If γ and T denotes the specific heat ratio and temperature, respectively the efficiency of the cycle is
In an Ideal Otto cycle the air standard efficiency is 56.5%. if the heat added during the constant volume process is 1000 kJ/kg, determine the work done.
In an Otto cycle, the compression ratio is 9 : 1 and the pressure and temperature at the beginning of the compression process are 100 kPa and 10°C. The heat addition by combustion gives the highest temperature as 2500 K.Thermal efficiency of the cycle is:
An Otto cycle has a compression ratio of 8. If 250 kJ of work is extracted from the cycle, the heat rejected by the cycle is
