Coefficient of Performance for Refrigeration Solution

Follow our step by step solution on how to calculate Coefficient of Performance for Refrigeration?

FIRST Step Consider the formula

βp = \frac{T low}{T high - T low}

Next Step Substitute values of Variables

∴

βp = \frac{10K}{100K - 10K}

Next Step Prepare to Evaluate

∴

βp = \frac{10}{100 - 10}

Next Step Evaluate

∴

βp = 0.111111111111111

LAST Step Rounding Answer

∴

βp = 0.1111
