Nusselt number for higher value of GrPr Solution

STEP 0: Pre-Calculation Summary
Formula Used
Average Nusselt Number upto L = 0.59*(Grashof Number*Prandtl Number)^0.25
NuavgL = 0.59*(G*Pr)^0.25
This formula uses 3 Variables
Variables Used
Average Nusselt Number upto L - Average Nusselt Number upto L is the ratio between heat transfer by convection (α) and heat transfer by conduction alone.
Grashof Number - Grashof number approximates the ratio of the buoyancy to viscous force acting on a fluid.
Prandtl Number - The Prandtl number (Pr) or Prandtl group is a dimensionless number, named after the German physicist Ludwig Prandtl, defined as the ratio of momentum diffusivity to thermal diffusivity.
STEP 1: Convert Input(s) to Base Unit
Grashof Number: 0.5 --> No Conversion Required
Prandtl Number: 0.7 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
NuavgL = 0.59*(G*Pr)^0.25 --> 0.59*(0.5*0.7)^0.25
Evaluating ... ...

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.
