Calculating Jet Pressure at Nozzle orifice
So i am using this 3HP pump for which the head ranges from 6 meters to 14 meters. Discharge being 19.1 LPS to 10.4 LPS respectively.
I am using a 2" pipe to carry the water upto a height of approx. 3 meters, which is then routed into a jet manifold containing number of jet nozzles.
The water is then sprayed out of these nozzles onto the component for washing.
So, my question is, what would be the pressure of the jet at the nozzle exit? And how do i calculate it?
Sorry if this is a stupid question
Any help would be appreciated.

The pressure at the exit of your nozzle would be zero because you're open to atmosphere. At this point you should be more interested in the fluid momentum which will be based off of fluid velocity. To caclulate the fluid velocity you would need to use Bernoulli's equation to take in consideration of the head ranges and the initial head or pressure the pump will provide.
Bernoulli's equation is P1+1/2ρv12+γz1=P2+1/2ρv22+γz2
You can learn more about Bernoulli's equation here Bernoulli's Equation
