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"
