1. What is Hydraulic Mean Depth?

Hydraulic Mean Depth of Triangular Section or hydraulic radius is the ratio of area of flow to the wetted perimeter. It is a fundamental parameter in open channel flow calculations and hydraulic engineering.

2. How Does the Calculator Work?

The calculator uses the hydraulic mean depth formula:

\[ H = \frac{y^2 \times (\theta + \cot(\theta))}{2 \times y \times (\theta + \cot(\theta))} \]

Where:

\( H \) — Hydraulic Mean Depth (m)
\( y \) — Depth of canal with trapezoidal cross section (m)
\( \theta \) — Side slope angle (radians)
\( \cot \) — Cotangent trigonometric function

Explanation: The formula calculates the hydraulic mean depth for triangular channel sections by considering the channel geometry and side slope characteristics.

3. Importance of Hydraulic Mean Depth

Details: Hydraulic mean depth is crucial for determining flow characteristics, calculating flow resistance, and designing efficient hydraulic structures in open channel flow systems.

4. Using the Calculator

Tips: Enter depth of canal in meters and side slope angle in radians. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of hydraulic mean depth?
A: Hydraulic mean depth represents the efficiency of a channel cross-section in conveying flow and is used in various hydraulic calculations including flow velocity and resistance.

Q2: How does side slope affect hydraulic mean depth?
A: The side slope angle directly influences the wetted perimeter and flow area, thereby affecting the hydraulic mean depth calculation.

Q3: What are typical values for side slope in channels?
A: Side slopes typically range from 1:1 to 2:1 (horizontal:vertical), depending on soil conditions and channel purpose.

Q4: Can this calculator be used for other channel shapes?
A: This specific calculator is designed for triangular channel sections. Different formulas apply for rectangular, trapezoidal, or circular sections.

Q5: Why use radians for angle measurement?
A: Trigonometric functions in mathematical calculations typically use radians as they provide more accurate results in computational applications.
