Diameter at which turbulence starts Solution

STEP 0: Pre-Calculation Summary

Formula Used

Diameter = ((5*10^5*Kinematic Viscosity)/(Rotational Speed))^(1/2)
D = ((5*10^5*u)/(w))^(1/2)
This formula uses 3 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.
Kinematic Viscosity - (Measured in Square Meter per Second) - The kinematic Viscosity is an atmospheric variable defined as the ratio between the dynamic viscosity μ and the density ρ of the fluid.
Rotational Speed - (Measured in Radian per Second) - Rotational Speed the number of turns of the object divided by time, specified as revolutions per minute.

STEP 1: Convert Input(s) to Base Unit

Kinematic Viscosity: 100 Stokes --> 0.01 Square Meter per Second (Check conversion here)
Rotational Speed: 5 Radian per Second --> 5 Radian per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D = ((5*10^5*u)/(w))^(1/2) --> ((5*10^5*0.01)/(5))^(1/2)

Evaluating ... ...

D = 31.6227766016838

STEP 3: Convert Result to Output's Unit

31.6227766016838 Meter --> No Conversion Required

FINAL ANSWER

31.6227766016838 ≈ 31.62278 Meter <-- Diameter

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.
