NuavgL = (5/4)*NuL
This formula uses 2 Variables
Variables Used
Average Nusselt Number - Average Nusselt number is the ratio between heat transfer by convection (α) and heat transfer by conduction alone.
Nusselt Number(L) - Nusselt number(L) is the ratio of convective to conductive heat transfer across a boundary.
STEP 1: Convert Input(s) to Base Unit
Nusselt Number(L): 0.25 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
NuavgL = (5/4)*NuL --> (5/4)*0.25
Evaluating ... ...
NuavgL = 0.3125

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.
