1. What is the Width of Section of Rect Channel?

The Width of Section of Rect Channel is the width of the rectangular cross-section of the beam parallel to the axis in consideration. It is an important parameter in hydraulic engineering for calculating flow characteristics in rectangular channels.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( B_{rect} \) — Width of Section of Rect Channel (m)
• \( A_{rect} \) — Wetted Surface Area of Rectangle (m²)
• \( D_f \) — Depth of Flow of Channel (m)

Explanation: The formula calculates the width of a rectangular channel section by dividing the wetted surface area by the depth of flow.

3. Importance of Channel Width Calculation

Details: Accurate calculation of channel width is crucial for hydraulic design, flow capacity estimation, and proper channel construction in water management systems.

4. Using the Calculator

Tips: Enter the wetted surface area in square meters and depth of flow in meters. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is wetted surface area in a rectangular channel?
A: Wetted surface area refers to the total area of the channel cross-section that is in contact with the flowing water.

Q2: How does depth of flow affect channel width calculation?
A: For a given wetted area, increasing the depth of flow decreases the required channel width, and vice versa.

Q3: Can this formula be used for non-rectangular channels?
A: No, this specific formula applies only to rectangular channel sections. Other channel shapes require different formulas.

Q4: What are typical units for these measurements?
A: The calculator uses meters for length measurements and square meters for area measurements, consistent with SI units.

Q5: How accurate is this calculation for real-world applications?
A: The calculation provides theoretical values. Actual channel design should consider additional factors such as flow velocity, sediment transport, and safety factors.
