Calculate Hydraulic Radius (R)



Formula

The formula to calculate the Hydraulic Radius (R) is:

\[ R = \frac{A}{P} \]

What is Hydraulic Radius?

A hydraulic radius is defined as the ratio of the cross-sectional area to the wetted perimeter of a hydraulic piston. It is an important parameter in fluid mechanics, particularly in the study of open channel flow and pipe flow, as it helps determine the efficiency of fluid flow.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Hydraulic Radius:

\[ R = \frac{2}{4} = 0.5 \text{ m} \]

The Hydraulic Radius is 0.5 m.
