Formula Used

Radiation Shape Factor 12 = (Surface Area of Body 2/Surface Area of Body 1)*Radiation Shape Factor 21
F₁₂ = (A₂/A₁)*F₂₁
This formula uses 4 Variables

Variables Used

Radiation Shape Factor 12 - Radiation Shape Factor 12 is the fraction of radiation energy radiated by one surface which is incident on another surface when both surfaces are placed in a non-absorbing medium.
Surface Area of Body 2 - (Measured in Square Meter) - The Surface Area of Body 2 is the area of body 2 upon which the radiation takes place.
Surface Area of Body 1 - (Measured in Square Meter) - The Surface Area of Body 1 is the area of body 1 through which the radiation takes place.
Radiation Shape Factor 21 - Radiation Shape Factor 21 is the fraction of radiation energy radiated by one surface which is incident on another surface when both surfaces are placed in a non-absorbing medium.

STEP 1: Convert Input(s) to Base Unit

Surface Area of Body 2: 50 Square Meter --> 50 Square Meter No Conversion Required
Surface Area of Body 1: 34.74 Square Meter --> 34.74 Square Meter No Conversion Required
Radiation Shape Factor 21: 0.41 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

F₁₂ = (A₂/A₁)*F₂₁ --> (50/34.74)*0.41

Evaluating ... ...

F₁₂ = 0.590097869890616

STEP 3: Convert Result to Output's Unit

0.590097869890616 --> No Conversion Required

FINAL ANSWER

0.590097869890616 ≈ 0.590098 <-- Radiation Shape Factor 12

What is Radiation?

Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You could also call radiation “electromagnetic waves”.

What is Blackbody?

A black body is defined as the body which absorbs all the electromagnetic radiation (that is light) that strikes it irrespective of the angle of incidence and frequency of the radiation.
