Here is how the Heat Rejection Factor equation looks like.

1.6 = \frac{1000 + 600}{1000}

1.6 = \frac{1000J/min + 600J/min}{1000J/min}

1.6 = \frac{1000 + 600}{1000}

Heat Rejection Factor Solution

Follow our step by step solution on how to calculate Heat Rejection Factor?

FIRST Step Consider the formula

HRF = \frac{R E + W}{R E}

Next Step Substitute values of Variables

∴

HRF = \frac{1000J/min + 600J/min}{1000J/min}

Next Step Convert Units

∴

HRF = \frac{16.6667J/s + 10J/s}{16.6667J/s}

Next Step Prepare to Evaluate

∴

HRF = \frac{16.6667 + 10}{16.6667}

LAST Step Evaluate

∴

HRF = 1.6

How to Evaluate Heat Rejection Factor?

Heat Rejection Factor evaluator uses Heat Rejection Factor = (Refrigeration Capacity+Compressor Work Done)/Refrigeration Capacity to evaluate the Heat Rejection Factor, Heat Rejection Factor formula is defined as a dimensionless quantity that characterizes the ability of a heat exchanger to reject heat from the hot fluid to the cold fluid, providing a measure of the heat exchanger's performance and efficiency in heat transfer applications. Heat Rejection Factor is denoted by HRF symbol.

How to evaluate Heat Rejection Factor using this online evaluator? To use this online evaluator for Heat Rejection Factor, enter Refrigeration Capacity (R_E) & Compressor Work Done (W) and hit the calculate button.
