air is entering a compressor at 373.15K and 500kPa, it exits the compressor at 520K and 1200Kpa. Calculate the heat capacity of the air (temperature dependent). and determine the residual enthalpy and entropy using the compressibility factor table of air, where z=PV/RT. Use double interpolation to get the compressibility factors.
