#### Formulas

##### 1. Relationship Between Pressure and Flow Rate

You can calculate the water quantity necessary for pressures not listed in the product list using the formula below.

##### 2.Relationship Between Pressure and Air Flow Rate

You can calculate the air quantity necessary for pressures not listed in the product list using the formula below.

##### 3.Impact Force of Water Jet (for descaling)

You can calculate the impact force necessary for descaling using the formula below.

The impact force for each unit area can be found as the average impact force through dividing the above with the spray area.

##### 4.Flow Rate Conversion Based On Specific Gravity

The flow rate will be different if using liquids other than water. After converting to the flow rate for water, use that number to select a nozzle from the Catalog.
