STEP 0: Pre-Calculation Summary
Formula Used
Heat Transfer Coefficient = (Biot Number*Thermal Conductivity)/Thickness of Wall
htransfer = (Bi*k)/𝓁
This formula uses 4 Variables
Variables Used
Heat Transfer Coefficient - (Measured in Watt per Square Meter per Kelvin) - Heat Transfer Coefficient is the heat transferred per unit area per degree celcius. Thus area is included in the equation as it represents the area over which the transfer of heat takes place.
Biot Number - Biot Number is a dimensionless quantity having the ratio of internal conduction resistance to the surface convection resistance.
Thermal Conductivity - (Measured in Watt per Meter per K) - Thermal Conductivity is rate of heat passes through specified material, expressed as amount of heat flows per unit time through a unit area with a temperature gradient of one degree per unit distance.
Thickness of Wall - (Measured in Meter) - The thickness of Wall refers to the distance between one surface of your model and its opposite sheer surface. Wall thickness is defined as the minimum thickness your model should have at any time.
STEP 1: Convert Input(s) to Base Unit
Biot Number: 2.19 --> No Conversion Required
Thermal Conductivity: 10.18 Watt per Meter per K --> 10.18 Watt per Meter per K No Conversion Required
Thickness of Wall: 4.99 Meter --> 4.99 Meter No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
htransfer = (Bi*k)/𝓁 --> (2.19*10.18)/4.99
Evaluating ... ...
