Convective Heat Transfer to Surface Solution

STEP 0: Pre-Calculation Summary
Formula Used
Convection Heat Transfer = [Stefan-BoltZ]*Emissivity*Temperature of wall in Kelvin^4-Radiative Heat Transfer
qconv = [Stefan-BoltZ]*ε*Tw^4-qrad
This formula uses 1 Constants, 4 Variables
Constants Used
[Stefan-BoltZ] - Stefan-Boltzmann Constant Value Taken As 5.670367E-8
Variables Used
Convection Heat Transfer - (Measured in Watt per Square Meter) - Convection Heat Transfer often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids.
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.
Temperature of wall in Kelvin - (Measured in Kelvin) - Temperature of wall in Kelvin is the wall temperature of the body under a flow.
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.
STEP 1: Convert Input(s) to Base Unit
Emissivity: 0.95 --> No Conversion Required
Temperature of wall in Kelvin: 357 Kelvin --> 357 Kelvin No Conversion Required
Radiative Heat Transfer: 97 Watt per Square Meter --> 97 Watt per Square Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
qconv = [Stefan-BoltZ]*ε*Tw^4-qrad --> [Stefan-BoltZ]*0.95*357^4-97
Evaluating ... ...
qconv = 777.999164110626
STEP 3: Convert Result to Output's Unit
777.999164110626 Watt per Square Meter --> No Conversion Required
FINAL ANSWER
777.999164110626 777.9992 Watt per Square Meter <-- Convection Heat Transfer
