Butterfly valves part II

[Bruce Plecan]

This is embarrassing, Doc been dancing around all night hoping someone would
send him a clue, but it hasn't happened (tha clue musk oil, stinks)
Anyway how do you use this chart?.
ie on a 2" pipe at 30d, how do you figure how much air is passing?

| I scanned it and posted to efi332.eng.ohio-state.edu/incoming
| as "flowbrws.jpg" and "flow.jpg".  The first is viewable and
| printable with a web browser. The second is a better quality
| one, but requires a nicer program (like Photoshop) to print on
| a single page.
