Unformatted text preview: 4) Determine the discharge through: a) An unsubmerged 9in. Parshall flume with Ha = 2.27 ft b) A 6ft Parshall flume with Ha = 2.6 ft and Hb = 2 ft. If you need to use correction factors in your calculations that are not available in your book, go to the US Bureau of Reclamation, and you can find correction factors in their publication: “Water Measurement Manual.” ( http://www.usbr.gov/pmts/hydraulics_lab/pubs/wmm/ ) 5) Design a Parshall flume to handle 10 mgd flow in a 4 ft wide channel at a downstream depth of 3.3 ft. If the channel floor is at elevation 73.4 ft, what is the water elevation upstream of the flume? What is the flume crest elevation? Include a design drawing and state all assumptions. (You can use page 129 in BJP for an example of the design drawing)....
