Hydraulic Radius Formula
The following equations are used to calculate the hydraulic radius and wetted perimeter.
R = A / P
- Where R is the hydraulic radius
- A is the cross-sectional area
- and P is the wetted perimeter.
In this case, we are assuming that the fluid is moving through a piper that is completely full. This means that the wetted perimeter is simply equal to the circumference of the piper, which can be calculated using equations for a circle. Typically the circumference of a circle is calculated using the radius, but since we are only given the cross-sectional area, the radius must be inferred from that information. This can be done by rearranging the formula.
Hydraulic Radius Definition
A hydraulic radius is defined as the ratio of the cross-section area to the wetted perimeter of a hydraulic piston.
