This nozzle sprays water in a fine mist (not odd smoke, it will wake the ground).
The water spray diameter is about 1.5 at the pressure of the tap water.
The flow rate of a single nozzle under the pressure of tap water is 3.5-5L/H.
The water pressure required for spraying is 1.5kg or more, which is the general tap water pressure. If it is water burning or water well, the show should be pressurized.
