The Reynolds number is the relationship between inertial forces (numerator) and viscious forces (demoninator).
The terms in the numerator are usually the fluid density, velocity, and "characteristic" dimension (which has units of length).
Depending on the type of problem you are trying to solve that characteristic dimension may be a length (flat plate problem) or a diameter (flow in a round tube), or hydraulic diameter (non-circular internal flow).
Since a non-circular cross section has more surface area than a circular cross section area there needs to be a way to account for this difference.
If you use the hydraulic diameter equation to calculate the hy. dia. of a circular cross section, you will get the diameter of the circle.

How do you calculate Reynolds number?
Reynolds' Number. Reynolds number is defined as, Re = ρVmD/μ where Vm is the average velocity at the inlet of a diffuser, D is the diameter (or equivalent diameter) of the diffuser inlet, and ρ and μ the density and viscosity of the test fluid
What is a circumference used for?

How do you calculate the field diameter of the medium power lens?
To calculate the field diameter of a medium power lens, you need to first determine the field number of the lens. The field number is typically provided by the manufacturer and represents the diameter of the field of view in millimeters. To calculate the field diameter, you divide the field number by the magnification of the lens. Field diameter = Field number / Magnification.

How do you calculate the diameter from the circumference?
The Circumference of a Circle when the diameter is a known, fixed number is Pi or about 3.14 multiplied by the Diameter 3.14 x D
What is the Graetz number?
The Graetz number is {(Diameter/Length)*Reynolds#*Prandtl#}^(1/3) It is used to characterize the thermal development of pipe flow: if the Graetz number is less than 1000, the thermal profile is fully developed.
