Default velocity injection
Posts: n/a

Can you please help me with the calculation of the injection velocity particles?

I know about the nozzle:

The orifice diameter 3mm

Operating pressure: 13 bar

Flow rate: 6lpm

Spary pattern: hollow cone

Spray angle: outer 90, inner 70

Sauter mean diameter: 121 micron

I approximate the velocity using the bernoulli's formula just by taking into account the pressure and the density of the water. Is this correct?

Thank you very much
