Flow of Water Over a V-Notch
Joseph TarrantAbstract
In this paper the author presents a formula for finding the flow of water over V-notches with angles ranging from 90 deg. down to 27 deg., which is based on the experimental results given in D. Robert Yarnall’s paper on the “Accuracy of the V-Notch-Weir Method of Measurement,” presented before the A.S.M.E. in December, 1926. He compares this formula with others which have been proposed, checks it with data obtained by several investigators, and concludes that, within the range of angles specified, it will prove useful. An alignment chart based on the formula is given, from which discharges may easily be read off.
