Total Emissive Power of Radiating Body Solution

STEP 0: Pre-Calculation Summary
Formula Used
Emissive Power per Unit Area = (Emissivity*(Effective Radiating Temperature)^4)*[Stefan-BoltZ]
Eb = (ε*(Te)^4)*[Stefan-BoltZ]
This formula uses 1 Constants, 3 Variables
Constants Used
[Stefan-BoltZ] - Stefan-Boltzmann Constant Value Taken As 5.670367E-8
Variables Used
Emissive Power per Unit Area - (Measured in Watt) - Emissive Power per Unit Area is the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy.
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.
Effective Radiating Temperature - (Measured in Kelvin) - Effective Radiating Temperature is the degree or intensity of heat present in a substance or object.
STEP 1: Convert Input(s) to Base Unit
Emissivity: 0.95 --> No Conversion Required
Effective Radiating Temperature: 85 Kelvin --> 85 Kelvin No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Eb = (ε*(Te)^4)*[Stefan-BoltZ] --> (0.95*(85)^4)*[Stefan-BoltZ]
Evaluating ... ...
Eb = 2.81196866310406
STEP 3: Convert Result to Output's Unit
2.81196866310406 Watt --> No Conversion Required
FINAL ANSWER
2.81196866310406 2.811969 Watt <-- Emissive Power per Unit Area

Basics of Modes of Heat Transfer Calculators

Radial Heat Flowing through Cylinder
​ Go Heat = Thermal Conductivity*2*pi*Temperature Difference*Length of Cylinder/(ln(Outer Radius of Cylinder/Inner Radius of Cylinder))
Heat Transfer through Plane Wall or Surface
​ Go Heat Flow Rate = -Thermal Conductivity*Cross Sectional Area*(Outside Temperature-Inside Temperature)/Width of Plane Surface
Radiative Heat Transfer
​ Go Heat = [Stefan-BoltZ]*Body Surface Area*Geometric View Factor*(Temperature of Surface 1^4-Temperature of Surface 2^4)
Total Emissive Power of Radiating Body
​ Go Emissive Power per Unit Area = (Emissivity*(Effective Radiating Temperature)^4)*[Stefan-BoltZ]
