Title: Venturi size graph and article in Flying Line by Dave Gardner and Pat Johnston
Post by: Steve Helmick on August 19, 2007, 08:27:08 PM

New tech data from Flying Lines, that you might find useful. Article by Dave Gardner, from data provided by Pat Johnston. The first link gets you to the article, the second to the technicalities, and the third to a venturi chart that will put you into the ballpark. Remember that you can start with a venturi on the large side and adjust from there via Bruline filters (fine or coarse) or layers of pantyhose stock applied with a small wiretie or o-ring.  D>K Steve
