During an Adiabatic compression in an engine, the volume is reduced to 0.0625 of its initial value. Heat is then added at constant pressure until the initial volume is attained again. The cycle is completed by a constant volume process. If at the beginning of the Adriatic compression the pressure is 9.0*10'4 (raised to power 4) and the temperature is 40*c.
I) Sketch the p-v diagram for the engine.
II) Calculate the thermal efficiency of the cycle taking cp =1.004kJ/K
