Coefficient of Performance given enthalpy of liquid refrigerant leaving condenser (hf3) Solution

Follow our step by step solution on how to calculate Coefficient of Performance given enthalpy of liquid refrigerant leaving condenser (hf3)?

FIRST Step Consider the formula

COP th = \frac{h 1 - h f3}{h 2 - h 1}

Next Step Substitute values of Variables

∴

COP th = \frac{260kJ/kg - 90kJ/kg}{350kJ/kg - 260kJ/kg}

Next Step Convert Units

∴

COP th = \frac{260000J/kg - 90000J/kg}{350000J/kg - 260000J/kg}

Next Step Prepare to Evaluate

∴

COP th = \frac{260000 - 90000}{350000 - 260000}

Next Step Evaluate

∴

COP th = 1.88888888888889

LAST Step Rounding Answer

∴

COP th = 1.8889
