More about: Well Flow Rate
What it calculates
The “Well Flow Rate” calculator computes Well yield in m³/h from 4 parameters: well depth (m), static water level (m), drawdown during pumping (m), pump rate during test (m³/h).
Applied in business management, unit economics, and financial modeling.
Example calculation
With parameters Well depth = 50 m, Static water level = 10 m, Drawdown during pumping = 5 m, Pump rate during test = 3 m³/h the result is 24 m³/h (Maximum (theoretical) yield; safe extraction is lower).
How to use
- Enter well depth, static water level, drawdown during pumping and pump rate during test — each field above is adjustable with a slider.
- Well yield (m³/h) is calculated automatically as you type.
- Check the worked example below to see the formula applied to real numbers.
