By Pass Factor - By Pass Factor is the inability of a coil to cool or heat the air to its temperature.

STEP 1: Convert Input(s) to Base Unit

Overall Heat Transfer Coefficient: 50 Watt per Square Meter per Kelvin --> 50 Watt per Square Meter per Kelvin No Conversion Required
Surface Area of Coil: 64 Square Meter --> 64 Square Meter No Conversion Required
Final Temperature: 345 Kelvin --> 345 Kelvin No Conversion Required
Initial Temperature: 105 Kelvin --> 105 Kelvin No Conversion Required
By Pass Factor: 0.85 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

SH = (U*A_c*(T_f-T_i))/ln(1/BPF) --> (50*64*(345-105))/ln(1/0.85)

Evaluating ... ...

SH = 4725603.36431772

STEP 3: Convert Result to Output's Unit

4725603.36431772 Joule --> No Conversion Required

FINAL ANSWER

4725603.36431772 ≈ 4.7E+6 Joule <-- Sensible Heat

SH = (U*A_c*(T_f-T_i))/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.
