Surface convection resistance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Surface Convection Resistance = Internal Conduction Resistance/Biot Number
R_sc = R_i/Bi
This formula uses 3 Variables

Variables Used

Surface Convection Resistance - (Measured in Kelvin per Watt) - Surface Convection Resistance is the resistance offered by the surface of the material for heat transfer by convection.
Internal Conduction Resistance - (Measured in Kelvin per Watt) - Internal Conduction Resistance is the resistance offered by the body for conduction of heat.
Biot Number - Biot Number is a dimensionless quantity having the ratio of internal conduction resistance to the surface convection resistance.

STEP 1: Convert Input(s) to Base Unit

Internal Conduction Resistance: 4 Kelvin per Watt --> 4 Kelvin per Watt No Conversion Required
Biot Number: 0.8 --> No Conversion Required

What is convection

Convection is the process of heat transfer by the bulk movement of molecules within fluids such as gases and liquids. The initial heat transfer between the object and the fluid takes place through conduction, but the bulk heat transfer happens due to the motion of the fluid.

Convection is the process of heat transfer in fluids by the actual motion of matter.
It happens in liquids and gases.
It may be natural or forced.
It involves a bulk transfer of portions of the fluid.
