Variables Used
Sensible Heat - (Measured in Joule) - Sensible Heat is a type of energy released or absorbed in the atmosphere.
Overall heat transfer coefficient - (Measured in Watt per Meter² per K) - Overall heat transfer coefficient is the overall convective heat transfer between a fluid medium (a fluid) and the surface (wall) flowed over by the fluid.
Surface Area of Coil - (Measured in Square Meter) - The Surface Area of Coil is the total area of the coil through which any fluid passes.
Final Temperature - (Measured in Kelvin) - Final Temperature is the measure of hotness or coldness of a system at its final state.
Initial Temperature - (Measured in Kelvin) - Initial Temperature is the measure of hotness or coldness of a system at its initial state.
By pass factor - By pass factor is the inability of a coil to cool or heat the air to its temperature.

## Sensible heat given out by coil using by-pass factor Formula

Sensible Heat = (Overall heat transfer coefficient*Surface Area of Coil*(Final Temperature-Initial Temperature))/ln(1/By pass factor)
Qsensible = (U*Ac*(Tf-Ti))/ln(1/BPF)

## 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.
