Resistance in Radiation Heat Transfer when No Shield is Present and Equal Emissivities Formula Elements

Variables

Resistance

Resistance for heat radiation is represented as the reciprocal of the product of the radiative heat transfer coefficient and the surface area of the object that generates heat.

Symbol: R

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Resistance

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.

Symbol: ε

Measurement: NAUnit: Unitless

Note: Value should be between 0 to 1.
