1. What is the Radius of Section given Hydraulic Radius Formula?

The formula calculates the radius of a channel section based on its hydraulic radius. The hydraulic radius is a fundamental parameter in fluid mechanics that represents the ratio of cross-sectional area to wetted perimeter.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( r' \) — Radius of Channel (m)
• \( R_H \) — Hydraulic Radius of Channel (m)

Explanation: This formula provides a direct conversion from hydraulic radius to the actual radius of the channel section, using a constant factor of 0.5733.

3. Importance of Radius Calculation

Details: Accurate radius calculation is essential for determining flow characteristics, designing efficient channel systems, and analyzing hydraulic performance in various engineering applications.

4. Using the Calculator

Tips: Enter the hydraulic radius value in meters. The value must be positive and valid for accurate calculation.
