The required water pressure at the nozzle in kN/m2 has been given as has the flow rate in m3/s. How do I work out the nozzle size?

If I could get a velocity I could use that in conjuction with flow rate to find the nozzle area.

Hi si1268.

Bernoulli devised an equation that might help you. Try a google search.
