Compression Ratio and Efficiency
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 750  kJ / kg of heat is transferred to air during the constant-volume heat-addition process. Taking into account the variation of specific heats with temperature, determine (a) the pressure and temperature at the end of the heat-addition process, (b) the net work output, (c) the thermal efficiency, and (d) the mean effective pressure for the cycle. | Numerade

In an air standard Diesel cycle, the compression ratio is 15 , and at the beginning of isentropic compression, the temperature is 27^∘ C and the pressure is 0.1 MPa. Heat is added until the temperature at the end of the constant pressure process is 1450^∘ C. For air, take cp=1.005  kJ / kg ·K and cv=0.718  kJ / kg ·K. Calculate (a) the cut-off ratio. (b) the heat supplied per kg of air. (c) the cycle efficiency. (d) the mean effective pressure in kPa. | Numerade
