Variables Used
Interchange Factor - Interchange factor is defined as the fraction of the energy leaving an isothermal area of a body that is incident upon the area of another body.
Emissivity of body 1 - Emissivity of body 1 is the ratio of the energy radiated from a body's surface to that radiated from a perfect emitter.
Emissivity of body 2 - Emissivity of body 2 is the ratio of the energy radiated from a body's surface to that radiated from a perfect emitter.
STEP 1: Convert Input(s) to Base Unit
Emissivity of body 1: 0.4 --> No Conversion Required
Emissivity of body 2: 0.3 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
f1-2 = ((1/ε1)+(1/ε2)-1)^(-1) --> ((1/0.4)+(1/0.3)-1)^(-1)
Evaluating ... ...

## What is Interchange factor?

Interchange factor is defined as the fraction of the energy leaving an isothermal area of a body that is incident upon the area of another body. It is also known as the Equivalent Emissivity.

## What is Emissivity?

Emissivity is defined as the ratio of the energy radiated from a material's surface to that radiated from a perfect emitter known as a blackbody, at the same temperature and wavelength and under the same viewing conditions. It is a dimensionless number between 0 (for a perfect reflector) and 1 (for a perfect emitter).
