Formula:
Hydraulic Gradient Calculation Formula: HG = (P2 - P1) / L
Categories/Types/Range/Hydraulic Gradients:
| Category/Type | Range (Imperial) | Range (SI) | Interpretation |
|---|---|---|---|
| Gentle Slope | 0.001 – 0.01 | 0.0001 – 0.001 | Mild inclines, lazy rivers. |
| Moderate Slope | 0.01 – 0.1 | 0.001 – 0.01 | Steeper terrain, moderate flow. |
| Steep Slope | > 0.1 | > 0.01 | Waterfalls, fast-flowing rapids. |
Examples of Hydraulic Gradient Calculations:
| Pressure Difference (P2 – P1) (psi) | Length (L) (ft) | Hydraulic Gradient (HG) (psi/ft) |
