Grashof Number Solution

STEP 0: Pre-Calculation Summary

Formula Used

Grashof Number = (Buoyant Force)/(Viscous Force)
G = (F_bu)/(μ_Force)
This formula uses 3 Variables

Variables Used

Grashof Number - Grashof number approximates the ratio of the buoyancy to viscous force acting on a fluid.
Buoyant Force - (Measured in Newton) - Buoyant Force is the upward force exerted by any fluid upon a body placed in it.
Viscous Force - (Measured in Newton) - Viscous Force is the force between a body and a fluid (liquid or gas) moving past it, in a direction so as to oppose the flow of the fluid past the object.

STEP 1: Convert Input(s) to Base Unit

Buoyant Force: 10.8 Newton --> 10.8 Newton No Conversion Required
Viscous Force: 107 Newton --> 107 Newton No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

G = (F_bu)/(μ_Force) --> (10.8)/(107)

Evaluating ... ...

G = 0.100934579439252

STEP 3: Convert Result to Output's Unit

0.100934579439252 --> No Conversion Required

FINAL ANSWER

0.100934579439252 ≈ 0.100935 <-- Grashof 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.
