Q.1 The air is compressed adiabatically in a combined piston-cylinder from 1 bar, 300 K to 10 bar, 600 K. Determine the work done, in kJ per kg of air, and the amount of entropy produced, in kJ/K per kg of air. The air is modeled as an ideal gas and the effects of the kinetic and potential energy are insignificant. What is the theoretical minimum work required for adiabatic compression from the initial state to the final pressure! given (Tatm-25C).
