Water Jet Nozzle Calculations

The velocity out of a free jet can be expressed as.

Water jet nozzle calculations.

V 2 velocity out of the jet m s. The nozzle calculation the conversion of the many units used in the water jetting technology and the support provided for the operation of the aquamat tank. The density ρ is constant in incompressible flows and the equations are valid for liquids like water but not for gases. This article provides calculation methods for correlating design flow rate and pressure loss as a fluid passes through a nozzle or orifice.

P 2 ambient pressure after the jet n m 2 pa. As a general rule the diameter of the orifice for the abrasive nozzle should be approximately three times the water nozzle orifice. Inputs to this calculator are the nozzle type current operating pressure and flow desired flow or desired pressure. Use this calculator to determine the flow rate of any nozzle at any operating pressure.

ρ density of the fluid kg m 3. Some people would suggest using a smaller ratio about 2 5 times. This calculating app enables you to evaluate a high pressure system from the high pressure pump through to the water jet nozzle. The water jetting calculator is a free of charge calculating app to water jetting technology.

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. 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. Specific gravity is the ratio of the density of a fluid compared to the density of water. Nozzles and orifices are often used to deliberately reduce pressure restrict flow or to measure flow rate.

V 2 2 p 1 p 2 ρ 1 2 1. The trade off is increased nozzle wear and costs. Using a smaller ratio does produce faster cutting speeds.
