A₂ = A₁*(F₁₂/F₂₁)
This formula uses 4 Variables

Variables Used

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 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.
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 1: 34.74 Square Meter --> 34.74 Square Meter No Conversion Required
Radiation Shape Factor 12: 0.59 --> No Conversion Required
Radiation Shape Factor 21: 0.41 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

A₂ = A₁*(F₁₂/F₂₁) --> 34.74*(0.59/0.41)

Evaluating ... ...

A₂ = 49.9917073170732

STEP 3: Convert Result to Output's Unit

49.9917073170732 Square Meter --> No Conversion Required

FINAL ANSWER

49.9917073170732 ≈ 49.99171 Square Meter <-- Surface Area of Body 2

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.
