Thanks very much for your help on this gentlemen. So,basically, if I wanted the pressure in the nozzle itself before the orifice I would use absolute pressure, but in terms of my application, whereby it's discharging to atmoshere, use of the gauges reading is acceptable.
This might be a stupid question. So gauge pressure is the pressure read on the actual pressure gauge on my pipe. Should I do it this way or should I use absolute pressure, which includes atmospheric pressure?
I've found a worked example on the net. Does the theory of P2=0 apply in my application.http://files.engineering.com/getfile.aspx?folder=a4e33bea-bce4-4336-893d-58286b830cec&file=Worked_example_of_discharge_to_atmosphere.pdf
That's what I'm trying to find out, the Cd. I've tested the nozzles and documented all the 'actual' flows at different pressures, read from the gauge. So to get the 'theoretical' flow rate should I use the specs from my pump to calculate that. These nozzles are newly developed, so they have no...
Hi there, I'm having a problem behind the theory of bernoulli's theorem. Can it be applied in an application where water flows from a pump into a pipe with x diameter and out of a nozzle with y diameter to atmosphere. There is a pressure gauge on said pipe. There is a nozzle screwed into this...
