I am working on a project at my summer internship rerouting some duct work and want to do some calculations to see how much changing some of the 90 degree angles in the duct will improve flow. I don't have my Fluids text with me and was wondering if anyone knew of any good references online to get the head loss coefficients for various duct shapes. Thanks.
