Use flow_rate=* for the nominal flow rate of a feature (a pipeline, a hydrant, a river).
A numeric value with its unit, in International System standard unit is m3/s.

Use with hydrants

For hydrants are preferable units like l/min (liters per minute), usgal/min (US gallons per minute), ukgal/min (UK gallons per minute), or m3/h (cubic meter per hour). e.g.: flow_rate=600 l/min
The use of usgal/min or ukgal/min instead of gpm is necessary because UK and US gallons are different.

Use in combination with
