Nusselt number for turbulent flow Solution

STEP 0: Pre-Calculation Summary

Formula Used

Nusselt Number = 0.10*((Grashof Number*Prandtl Number)^0.333)
Nu = 0.10*((G*Pr)^0.333)
This formula uses 3 Variables

Variables Used

Nusselt Number - The Nusselt Number is the ratio of convective to conductive heat transfer at a boundary in a fluid. Convection includes both advection and diffusion.
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

Nu = 0.10*((G*Pr)^0.333) --> 0.10*((0.5*0.7)^0.333)

Evaluating ... ...

Nu = 0.07049765300325

STEP 3: Convert Result to Output's Unit

0.07049765300325 --> No Conversion Required

FINAL ANSWER

0.07049765300325 ≈ 0.070498 <-- Nusselt Number

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.
