Heat Transfer Efficiency Solution

Follow our step by step solution on how to calculate Heat Transfer Efficiency?

FIRST Step Consider the formula

α = \frac{h net}{H}

Next Step Substitute values of Variables

∴

α = \frac{20KJ}{21.05KJ}

Next Step Convert Units

∴

α = \frac{20000J}{21050J}

Next Step Prepare to Evaluate

∴

α = \frac{20000}{21050}

Next Step Evaluate

∴

α = 0.950118764845606

LAST Step Rounding Answer

∴

α = 0.9501

How to Evaluate Heat Transfer Efficiency?

Heat Transfer Efficiency evaluator uses Heat Transfer Efficiency = Net Heat Supplied/Heat Generated to evaluate the Heat Transfer Efficiency, Heat Transfer Efficiency is a measure of how effectively heat is transferred from one system or substance to another. It is often expressed as a ratio or percentage, comparing the actual amount of heat transferred to the maximum possible amount of heat that could be transferred under ideal conditions. Heat Transfer Efficiency is denoted by α symbol.
