An ideal Otto cycle has a compression ratio of 8. At the beginning of the compression process, air is at 95 kPa and 27°C, and 800 kJ/kg of heat is transferred to air during the constant-volume heat-addition process. Take into account the variation of specific heats with temperature. The gas constant of air is R = 0.287 kJ/kg-K. Determine the mean effective pressure for the cycle. The mean effective pressure for the cycle is 0 kPa.
An air standard diesel cycle has a compression ratio of 13 and a peak combustion temperature of 1681.55 C. If the heat rejected by the engine amounts to 3kW, determine the theoretical output power that can be produced by the engine.
THERMODYNAMICS The compression ratio of an air-standard dual cycle is 14 and the cutoff ratio is 1.2. During the constant-volume heat addition process, the pressure ratio is 1.5.
