Micro Hydro Power Calculator

Estimate and optimize your micro hydropower system output based on site parameters

System Parameters

Static Head (m):

Pipe Internal Diameter (mm): i Internal diameter of your penstock pipe. For MDPE blue metric pipes:

Pipe Length (m):

Pipe Material:

System Efficiency (%):

Custom Flow Rate (L/s, optional):

0.65 L/s

This is the flow rate that maximizes power output for your system parameters.

51.8 watts

Theoretical maximum electrical output at optimal flow.

16.23 meters

Effective head after friction losses.

The curve shows how power output changes with flow rate. The peak represents the optimal operating point.

This chart shows how static head, head loss, and net head vary with flow rate.
