1. What is Depth of Flow Calculation?

The depth of flow calculation determines the vertical distance from the water surface to the bottom of a channel in a triangular section, based on the wetted perimeter and the channel angle.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( p \) — Wetted Perimeter of Channel (m)
• \( \theta \) — Theta angle (radians)
• \( \cot \) — Cotangent trigonometric function

Explanation: The formula calculates the depth of flow in a triangular channel section by considering the wetted perimeter and the channel angle, using trigonometric relationships.

3. Importance of Depth of Flow Calculation

Details: Accurate depth of flow calculation is essential for hydraulic engineering, channel design, flood management, and water resource planning in triangular channel sections.

4. Using the Calculator

Tips: Enter wetted perimeter in meters and theta angle in radians. Both values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is wetted perimeter?
A: Wetted perimeter is the length of the channel bottom and sides that are in contact with water.

Q2: Why is theta angle important?
A: Theta angle defines the shape and slope of the triangular channel section, which directly affects the depth of flow calculation.

Q3: What units should be used for inputs?
A: Wetted perimeter should be in meters and theta angle should be in radians for consistent results.

Q4: Can this formula be used for other channel shapes?
A: No, this specific formula is designed for triangular channel sections only.

Q5: What if my theta angle is in degrees?
A: You'll need to convert degrees to radians first (radians = degrees × π/180) before using the calculator.
