Hi all,
i got this nozzle from an online store where it can creates a flat-pan shape of water or air at the exit. The inlet is 1/4" male to a 0.91 diameter (from catalog).but the problem is from the photo, it's not a circular orifice.
Can anyone help to calculate the flow-rate if the nozzle outlet area i assume to be rectangular in shape with 0.91(L) and 0.6(W) when it is connected to a air compressor with supply of pressure at 5 bar.
Thank you for helping. THX A LOT!!!

Contact the online store and ask them for the manufacturer and model number of what you bought. Then, consult that manufacturer's website. More than likely, they will give you tabulated data or equations. Or, match it up to equivalent Spraying Systems or Betz nozzles.

If it was McMaster-Carr, they'll send you cut sheets on the items you purchased if you request.

Good luck,
Latexman

To a ChE, the glass is always full - 1/2 air and 1/2 water.

Contact the manufacturer. They know what the flow rate is. That information would be in the catalog.

You need to know V angle and size. This give the equivalent orifice diameter.

For air just put that diameter into a choked flow orifice calculation and away you go.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

Pretty much a guess...but the number stamped on the end of the nozzle is likely the rated GPM at 100 psi or so.

You could also plumb the nozzle to a hose with a pressure gauge, connect the other end to a pressurized water source and squirt the output into a bucket, and time the flow with a stopwatch...
