Do not copy from anywhere... I will put more dislikes. And i will report.

Example 4.5. Find the theoretical C.O.P. for a co, machine working between the temperature range of 25C and 5C. The dryness fraction of Co, gas during the suction stroke is 0.6. Following properties of Co, are given : Temperature C Latent heat kJ/kg Liquid Enthalpy Entropy kJ/kg kJ/kg K 164.77 0.5978 72.57 0.2862 Vapour Enthalpy Entropy kJ/kg kJ/kg K 282.23 0.9918 321.33 1.2146 25 -5 117.46 248.76
