...Got the butterfly valve flow rate fax. Thanks Dave (TurboDave, right?). 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. later, -greg
