COP of Bell-Coleman Cycle for given Temperatures, Polytropic Index and Adiabatic Index Solution

Follow our step by step solution on how to calculate COP of Bell-Coleman Cycle for given Temperatures, Polytropic Index and Adiabatic Index?

FIRST Step Consider the formula

COP theoretical = \frac{T 1 - T 4}{(\frac{n}{n - 1}) \cdot (\frac{γ - 1}{γ}) \cdot ((T 2 - T 3) - (T 1 - T 4))}

Next Step Substitute values of Variables

∴

COP theoretical = \frac{300K - 290K}{(\frac{1.52}{1.52 - 1}) \cdot (\frac{1.4 - 1}{1.4}) \cdot ((356.5K - 326.6K) - (300K - 290K))}

Next Step Prepare to Evaluate

∴

COP theoretical = \frac{300 - 290}{(\frac{1.52}{1.52 - 1}) \cdot (\frac{1.4 - 1}{1.4}) \cdot ((356.5 - 326.6) - (300 - 290))}

Next Step Evaluate

∴

COP theoretical = 0.601692673895796

LAST Step Rounding Answer

∴

COP theoretical = 0.6017
