In the Otto cycle the initial pressure and temperature of compression are 100 kPa and 40C, it is known that the compression volume ratio is 6:1 and the heat supplies per cycle is 1000 kJ/kg. The working fluid is air with Cv=0.718 kJ/kgK, and =1.4.

Determine:

a) P-v diagram of the Otto cycle

b) Cycle maximum temperature

c) work done

d) Released calories

e) Cycle thermal efficiency
