Flow Rate Calculator


Use this calculator to determine the flow rate of any nozzle at any operating pressure. Inputs to this calculator are the nozzle type, current operating pressure and flow, desired flow or desired pressure.

Equation


Nozzle flow rate varies with spraying pressure. In general, the relationship between flow rate and pressure is as follows:
