To determine the potential of your water mill, you must evaluate several key parameters that influence hydraulic power production:
1. Stream flow (Q)
Flow rate is the amount of water that passes through a cross section of the stream per unit time. It is usually measured in cubic meters per second (m³/s).
2. Drop height (H)
The head is the difference in height between the water level at the entrance to the mill and the level at the outlet. It is generally measured in meters (m).
3. System efficiency (η)
The overall efficiency takes into account mechanical, hydraulic and electrical losses in the system. This factor depends on the efficiency of the different components of the mill and is typically between 0.5 and 0.9 for small installations.
