Efficiency of Heating Coil Formula

Efficiency = (Final Temperature-Initial Temperature)/(Temperature of Coil-Initial Temperature)
η = (T_f-T_i)/(T_c-T_i)

What is By-pass factor?

The inability of a coil to cool or heat the air to its temperature is indicated by a factor called the by-pass factor (BPF) or Coil Bypass Factor. This inability is due to the coil inefficiency and some amount of air just bypassing the coil without getting affected by it. A coil with low BPF has better performance. BPF can also be defined as the ratio of air that is unaffected by the coil to the total quantity of air passing over the coil.

FAQ

What is Efficiency of Heating Coil?

The Efficiency of heating coil formula is defined as the ability of the coil to heat the air that passes through it and is represented as η = (T_f-T_i)/(T_c-T_i) or Efficiency = (Final Temperature-Initial Temperature)/(Temperature of Coil-Initial Temperature). Final Temperature is the measure of hotness or coldness of a system at its final state, Initial Temperature is the measure of hotness or coldness of a system at its initial state & The Temperature of Coil is the temperature at which the coil is used for heating or cooling of fluid that passes through it.

How to calculate Efficiency of Heating Coil?

The Efficiency of heating coil formula is defined as the ability of the coil to heat the air that passes through it is calculated using Efficiency = (Final Temperature-Initial Temperature)/(Temperature of Coil-Initial Temperature). To calculate Efficiency of Heating Coil, you need Final Temperature (T_f), Initial Temperature (T_i) & Temperature of Coil (T_c). With our tool, you need to enter the respective value for Final Temperature, Initial Temperature & Temperature of Coil and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Efficiency?

In this formula, Efficiency uses Final Temperature, Initial Temperature & Temperature of Coil. We can use 3 other way(s) to calculate the same, which is/are as follows -

Efficiency = 1-By Pass Factor
Efficiency = 1-By Pass Factor
Efficiency = (Initial Temperature-Final Temperature)/(Initial Temperature-Temperature of Coil)
