Thanks Jim... I don't doubt that you're right. I'm just thinking about a banjo fitting I'm looking at right now... the flow path is through the hollow bolt, then exits through 3 equally spaced holes around the circumference of the bolt into the "banjo chamber" (for lack of a different term). The combined area of those 3 holes exceeds the I.D. of the outlet barb by quite a bit. Also, any one of those 3 holes is probably going to be very close to the inlet of the barb. Some banjo fittings may have only 1 or 2 holes. I don't want to bore anyone, and you're right... it's probably not worth worrying about. I do always appreciate your knowledge of hydraulics.
