Hydraulic Gradient Calculator

Find the hydraulic gradient from head loss and length.

Head loss

Flow length

Hydraulic gradient 0.02

Formula: i = head loss ÷ length

Step-by-step with your numbers:

1. Values used:

2. Head loss = 2

3. Flow length = 100

5. Hydraulic gradient = Head loss / Flow length = 2 / 100 = 0.02

Did we solve your problem today?

The hydraulic gradient is the drop in head per unit length of flow path.

The math behind it

i = Δh ÷ L. It drives flow in Darcy's law and pipe friction calculations.

2 m head loss over 100 m → gradient 0.02.

Where is it used?

Groundwater flow, pipe design and open-channel slope analysis.
