Ambient air temperature and pressure = 20°C and 0.8 bar.

Ram air pressure = 0.9 bar

Compressor outlet pressure = 3.6 bar

Temperature of air leaving H.E. -7.60°C

Pressure of air leaving the turbine = 1 bar

Temperature of air leaving the cabin = 2 2'C

Compressor and Turbine efficiency = 8O % and 75 % resin.

Assume no pressure drop in HE, and isentropic ramming process. Calculate net power required and COP of the system.
