Thermodynamic

In a piston-cylinder air at 100 kPa and 15°C undergoes thefollowing cycle. First, it is compressed isentropically to acompression ratio of 20. Then 1800
kJ/kg of heat is transferred to the air at constant pressure.Afterwards the air expands isentropically. In the last step, heatis removed at constant volume until the air reaches its originalstate. Assuming air behaves as an ideal gas and with Cp and Cvindependent of temperature, determine the:
(a) pressure and temperature at each point in the cycle,
(b) thermal efficiency of the cycle, and
(c) mean effective pressure.

Please work by step and orderly to easy work
