Q2. Two kilograms of air within a piston-cylinder configuration execute a Carnot power cycle between temperatures 750 K and 300 K. The isothermal expansion is associated with a heat input of 60 kJ from the surroundings. The volume after expansion has occurred isothermally is 0.4 m3 . Assuming air behaves as an ideal gas, calculate: (i) thermal efficiency for the cycle (ii) pressure and volume at the beginning of the isothermal expansion, in kPa and m3 , respectively. (iii) the work and heat transfer for each of the four processes, in kJ.

Thermodynamic In a piston-cylinder air at 100 kPa and 15°C undergoes the following cycle. First, it is compressed isentropically to a compression 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, heat is removed at constant volume until the air reaches its original state. Assuming air behaves as an ideal gas and with Cp and Cv independent of temperature, determine the: (a) pressure and...
