1. Relational expression between pressure and flow rate

Use the following equation to calculate flow rate in different pressures than the one in our model number list.
　　*Only for hydraulic nozzle (flat and straight pattern)

2. Relational expression between pressure and air flow rate

Use the following equation to calculate air flow rate in different pressures than the one in our model number list.

3. Spray water impact force (for descaling nozzle)

Use the following equation to calculate impact force of descaling nozzle.

Impact force per unit area is calculated as the mean impact force by dividing the above value by the spray area.

4.Flow rate conversion by specific gravity

The flow rate might change, depending on the specific gravity of the liquid. Select the suitable nozzle model numbers from our catalog by converting into water base flow rate if the liquid is not water.
