Title: Nozzle Size
Post by: AF150 on October 19, 2014, 05:29:06 PM

Spud...
Could you post a chart showing the true decimal diameters of Hilborn nozzles? I have (4) 104A
and I don't know how to calculate total nozzle area.
Thanks

 ...and then I realized the nozzle you wanted wasn't on the chart :)

 Multiply the Hilborn size times 59, take the square root and divide by 1000...that'll get you very close.

 (SQRT(Hilborn Size * 59))/1000

 Your 104 nozzles = .0783"
