An air standard Carnot cycle is executed in a closed system

An air standard Carnot cycle is executed in a closed system between the temperature limits of350 K and 1200 K. The pressure before and after the isothermal compression are 150 kPa and 300 kPa respectively. The net work output per cycle is 0.5 kJ . Use the IG model for air.

a. Determine the maximum pressure in the cycle.

b. Determine the heat transfer to air.

c. Determine the mass of air.
