1. What is the Discharge Calculation for Triangular Channel?

The discharge calculation for a triangular channel determines the rate of flow of a liquid through a triangular-shaped open channel. It uses the critical depth and bed slope to compute the discharge rate, which is essential in hydraulic engineering and water resource management.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Discharge of Channel (m³/s)
• \( h_t \) — Critical Depth of Triangular Channel (m)
• \( S \) — Bed Slope (-)
• \( g \) — Gravitational acceleration (9.80665 m/s²)

Explanation: The formula calculates the discharge based on the fifth power of critical depth and the square of bed slope, adjusted by the gravitational constant.

3. Importance of Discharge Calculation

Details: Accurate discharge calculation is crucial for designing irrigation systems, flood control measures, and managing water resources in open channels.

4. Using the Calculator

Tips: Enter the critical depth in meters and bed slope as a dimensionless value. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is critical depth in a triangular channel?
A: Critical depth is the depth at which the specific energy is minimum for a given discharge in a triangular channel.

Q2: How does bed slope affect discharge?
A: A steeper bed slope generally increases the discharge rate due to higher flow velocity.

Q3: What are typical values for bed slope?
A: Bed slope values typically range from 0.0001 to 0.01, depending on the channel material and design.

Q4: Are there limitations to this formula?
A: This formula assumes uniform flow conditions and may not be accurate for rapidly varying flow or non-triangular channel shapes.

Q5: Can this calculator be used for other channel shapes?
A: No, this specific formula is designed for triangular channels only. Other channel shapes require different formulas.
