Q7 The initial condition for an air-standard Otto cycle operating with acompression ratio of (8:1) are (0.95bar) and (17 °C). At the beginning of the compression stroke, the Cylinder volume is (3.8 103 m³) and (7.5Kj) of heat are added to the gas. Calculate the Pressure and temperature at the end of each process and determine the thermal efficiency and mean effective pressure of the cycle.
