PROBLEM $5$

Air as an ideal gas execute a carnot cycle while operating between thermal reservoirs at $1200$ K and

$600$ K $.$ The pressure at the initial and final states of the isothermal expansion process are $5000$ kPa

and $3000$ kPa $.$ Determine pressures at initial and final states of isothermal compression. Determine

heat and work process for each of the four processes. Determine the thermal efficiency. Assume

mass flow rate of air as $m=1k\frac{g}{s}$

Carnot cycle can beconstructed by using air as working fluid by using an isothermal turbine, an

isothermal compressor, an isentropic turbine an an isentropic compressor.
