Resources Water Jet Reference Tables

Water Jet Reference Tables

To determine the flow of a standard NLB nozzle at any given pressure, just click on the corresponding table below.

We’ve also provided tables to tell you the theoretical nozzle thrust at a variety of pressures and flows, and the pressure drop you can expect when using hoses of different diameters.

Finally, there’s a helpful conversion chart with English and metric equivalents for pressure, flow, weight, hp, and more.
