An air cycle refrigeration plant operates with a centrifugal compressor and an air turbine- mounted coaxially such that the power output from the turbine contributes to the power required to drive the compressor. The temperature of the air at the compressor inlet is 15°C and the pressure ratio is 2.5. The air during its passage from the compressor to the turbine passes through an intercooler and enters the turbine at 40°C. The cold space temperature is required to be maintained at 15°C. Taking the isentropic efficiency of bot compressor and turbine to be 84% and the mechanical efficiency of the turbine- compressor drive as 90%, calculate the following:
