In an Otto cycle air is compressed from an initialpressure 120 kPa and temperature 370 T (K). The cycle hascompression ratio of 10. In the constant volume heat additionprocess 1000 kJ/kg heat is added into the air. Consideringvariation on the specific heat of air with temperature,determine,
(a) the pressure and temperature at the end of heataddition process (show the points on P-v diagram)
(b) the network output
(c) the thermal efficiency
(d) the mean effective pressure for thecycle.
The gas constant of air is R = 0.287kJ/kg.K
