This formula uses 1 Constants, 4 Variables
Constants Used
[Stefan-BoltZ] - Stefan-Boltzmann Constant Value Taken As 5.670367E-8
Variables Used
Radiative Heat Transfer - (Measured in Watt per Square Meter) - Radiative Heat Transfer is the Heat transfer through radiation takes place in form of electromagnetic waves mainly in the infrared region.
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.
Wall Temperature - (Measured in Kelvin) - Wall Temperature is the temperature at the wall.
Heat Transfer by Convection - Heat transfer by convection is heat transfer by mass motion of a fluid such as air or water.
STEP 1: Convert Input(s) to Base Unit
Emissivity: 0.95 --> No Conversion Required
