Diameter given Graetz number Solution

STEP 0: Pre-Calculation Summary

Formula Used

Diameter = Graetz Number*Length/(Reynolds Number*Prandtl Number)
D = Gr*L/(Re*Pr)
This formula uses 5 Variables

Variables Used

Diameter - (Measured in Meter) - Diameter is a straight line passing from side to side through the center of a body or figure, especially a circle or sphere.
Graetz Number - Graetz number is used in determining the thermally developing flow entrance length in ducts.
Length - (Measured in Meter) - Length is the measurement or extent of something from end to end.
Reynolds Number - Reynolds Number is a dimensionless number used in fluid mechanics to indicate whether fluid flow past a body or in a duct is steady or turbulent.
Prandtl Number - Prandtl Number 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

Graetz Number: 800 --> No Conversion Required
Length: 3 Meter --> 3 Meter No Conversion Required
Reynolds Number: 5000 --> No Conversion Required
Prandtl Number: 0.7 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D = Gr*L/(Re*Pr) --> 800*3/(5000*0.7)

Evaluating ... ...

D = 0.685714285714286

STEP 3: Convert Result to Output's Unit

0.685714285714286 Meter --> No Conversion Required

FINAL ANSWER

0.685714285714286 ≈ 0.685714 Meter <-- Diameter

D = Gr*L/(Re*Pr)

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.
