J = (ε*E_b)+(ρ*G)
This formula uses 5 Variables

Variables Used

Radiosity - (Measured in Watt per Square Meter) - Radiosity represents the rate at which radiation energy leaves a unit area of a surface in all directions.
Emissivity - Emissivity is the ability of an object to emit infrared energy. Emissivity can have a value from 0 (shiny mirror) to 1.0 (blackbody). Most organic or oxidized surfaces have emissivity close to 0.95.
Emissive Power of Blackbody - (Measured in Watt per Square Meter) - Emissive Power of Blackbody is the energy of thermal radiation emitted in all directions per unit time from each unit area of a surface of blackbody at any given temperature.
Reflectivity - Reflectivity is the fraction of incident radiation flux reflected by the body.
Irradiation - (Measured in Watt per Square Meter) - Irradiation is the radiation flux incident on a surface from all directions.

STEP 1: Convert Input(s) to Base Unit

Emissivity: 0.95 --> No Conversion Required
Emissive Power of Blackbody: 324.29 Watt per Square Meter --> 324.29 Watt per Square Meter No Conversion Required
Reflectivity: 0.1 --> No Conversion Required
Irradiation: 0.8 Watt per Square Meter --> 0.8 Watt per Square Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

J = (ε*E_b)+(ρ*G) --> (0.95*324.29)+(0.1*0.8)

Evaluating ... ...

J = 308.1555

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.

How to Calculate Radiosity given Emissive Power and Irradiation?

Radiosity given Emissive Power and Irradiation calculator uses Radiosity = (Emissivity*Emissive Power of Blackbody)+(Reflectivity*Irradiation) to calculate the Radiosity, The Radiosity given Emissive Power and Irradiation formula is defined as the summation of reflected part of the incoming radiation and emissive power of non blackbody. Radiosity is denoted by J symbol.
