1. What is the Side Slope of Channel Given Critical Depth for Triangular Channel?

The Side Slope of Channel Given Critical Depth for Triangular Channel calculation determines the bed slope required for critical flow conditions in a triangular channel. This is essential for designing efficient hydraulic structures and understanding flow behavior in open channels.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Bed Slope = \left( \frac{2 \times (Discharge\ of\ Channel)^2}{(Critical\ Depth\ of\ Triangular\ Channel^5) \times [g]} \right)^{1/2} \]

Where:

\( Discharge\ of\ Channel \) — Rate of flow of liquid (m³/s)
\( Critical\ Depth\ of\ Triangular\ Channel \) — Depth where energy is at minimum for a particular discharge (m)
\( [g] \) — Gravitational acceleration constant (9.80665 m/s²)

Explanation: The equation calculates the required bed slope to maintain critical flow conditions in a triangular channel based on discharge and critical depth parameters.

3. Importance of Bed Slope Calculation

Details: Accurate bed slope calculation is crucial for designing efficient drainage systems, irrigation channels, and hydraulic structures. It ensures optimal flow conditions and prevents issues like sediment deposition or erosion.

4. Using the Calculator

Tips: Enter discharge in m³/s and critical depth in meters. All values must be positive and valid for accurate calculation results.
