Nusselt number for medium aspect ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Nusselt Number(L) Based on Length = (0.22*((Prandtl Number*Rayleigh Number Based on Length)/(0.2+Prandtl Number))^0.28)*(Height of Crack/Length)^-0.25
Nu_L = (0.22*((Pr*RaL)/(0.2+Pr))^0.28)*(h/L)^-0.25
This formula uses 5 Variables

Variables Used

Nusselt Number(L) Based on Length - Nusselt Number(L) Based on Length is the ratio of convective to conductive heat transfer across a boundary.
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.
Rayleigh Number Based on Length - Rayleigh Number Based on Length is a dimensionless parameter that is a measure of the instability of a layer of fluid due to differences of temperature and density at the top and bottom.
Height of Crack - (Measured in Meter) - Height of Crack is the size of a flaw or crack in a material that can lead to catastrophic failure under a given stress.
Length - (Measured in Meter) - Length is the measurement or extent of something from end to end.

STEP 1: Convert Input(s) to Base Unit

Prandtl Number: 0.7 --> No Conversion Required
Rayleigh Number Based on Length: 0.35 --> No Conversion Required
Height of Crack: 12000 Millimeter --> 12 Meter (Check conversion here)
Length: 3 Meter --> 3 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Nu_L = (0.22*((Pr*RaL)/(0.2+Pr))^0.28)*(h/L)^-0.25 --> (0.22*((0.7*0.35)/(0.2+0.7))^0.28)*(12/3)^-0.25

Evaluating ... ...

Nu_L = 0.108065305106637

STEP 3: Convert Result to Output's Unit

0.108065305106637 --> No Conversion Required

FINAL ANSWER

0.108065305106637 ≈ 0.108065 <-- Nusselt Number(L) Based on Length

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.
