This formula uses 1 Constants, 4 Variables
Constants Used
pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288
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.
Reynolds Number(w) - Reynolds number(w) is a dimensionless number used in fluid mechanics to indicate whether fluid flow past a body or in a duct is steady or turbulent.
Kinematic Viscosity - (Measured in Square Meter per Second) - Kinematic Viscosity is the ratio between the dynamic viscosity μ and the density ρ of the fluid.
Rotational Speed - (Measured in Radian per Second) - Rotational Speed is the number of turns of the object divided by time, specified as revolutions per minute.
STEP 1: Convert Input(s) to Base Unit
Reynolds Number(w): 0.6 --> No Conversion Required
Kinematic Viscosity: 4 Megastokes --> 400 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 = ((Rew*vk)/(pi*w))^(1/2) --> ((0.6*400)/(pi*5))^(1/2)
Evaluating ... ...
D = 3.90882009522336
STEP 3: Convert Result to Output's Unit
3.90882009522336 Meter --> No Conversion Required
FINAL ANSWER
3.90882009522336 3.90882 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.
