Water Jet Nozzle Calculations

The hammelmann water jetting calculator is a free of charge app for water jet technology.

Water jet nozzle calculations. Using a smaller ratio does produce faster cutting speeds. V 2 2 p 1 p 2 ρ 1 2 1. Inputs to this calculator are the nozzle type current operating pressure and flow desired flow or desired pressure. Sprinkler calculator finds the nozzle discharge flow rate for a given diameter and pressure or the diameter size for a given pressure and flow rate.

The app is used to assess your high pressure system from the high pressure pump all the way through to a suitable nozzle insert and takes into account all parameters for a safe and customized configuration of your system. The specific gravity of water is 1. Nozzles and orifices are often used to deliberately reduce pressure restrict flow or to measure flow rate. As a general rule the diameter of the orifice for the abrasive nozzle should be approximately three times the water nozzle orifice.

Specific gravity is the ratio of the density of a fluid compared to the density of water. The density ρ is constant in incompressible flows and the equations are valid for liquids like water but not for gases. Use this calculator to determine the flow rate of any nozzle at any operating pressure. This article provides calculation methods for correlating design flow rate and pressure loss as a fluid passes through a nozzle or orifice.

The trade off is increased nozzle wear and costs. P 2 ambient pressure after the jet n m 2 pa. P 1 pressure before the jet n m 2 pa. The water jetting calculator is a free of charge calculating app to water jetting technology.

This calculating app enables you to evaluate a high pressure system from the high pressure pump through to the water jet nozzle. V 2 velocity out of the jet m s. ρ density of the fluid kg m 3.
