1. What is Depth of Flow for Wetted Perimeter for Triangle?

The Depth of Flow for Wetted Perimeter for Triangle calculation determines the vertical distance from the water surface to the channel bottom in a triangular channel section, based on the wetted perimeter and side slope characteristics.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Wetted Perimeter — Length of channel surface in contact with water (m)
• Side Slope — Horizontal distance per unit vertical drop (-)

Explanation: This formula calculates the flow depth in triangular channels by considering the geometric relationship between wetted perimeter and channel side slopes.

3. Importance of Depth Calculation

Details: Accurate depth calculation is essential for hydraulic design, flow capacity estimation, and channel stability analysis in triangular open channels.

4. Using the Calculator

Tips: Enter wetted perimeter in meters and side slope as a dimensionless ratio. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is wetted perimeter in channel flow?
A: Wetted perimeter is the total length of the channel boundary that is in contact with the flowing water.

Q2: How is side slope defined for triangular channels?
A: Side slope represents the horizontal distance per unit vertical drop, typically expressed as z:1 where z is the horizontal distance.

Q3: What are typical side slope values for triangular channels?
A: Common side slopes range from 1:1 to 3:1 depending on soil stability and construction requirements.

Q4: Can this formula be used for partially filled triangular channels?
A: Yes, this formula applies to both fully and partially filled triangular channels.

Q5: What are the limitations of this calculation?
A: This calculation assumes uniform flow conditions and may not account for irregular channel shapes or varying roughness coefficients.
