Abstract :
A new form of weir and a simple, straight-line formula have been devised by Clemens Herschel, Past-President, Am. Soc. C. E., for gaging the flow of water in open channels. This weir and the accompanying formula are results of experiments made by Mr. Herschel with the support of Engineering Foundation, at the laboratory of Massachusetts Institute of Technology. A report of the experiments was presented in the form of a paper to the American Society of Mechanical Engineers, and was printed in full in “Mechanical Engineering” for February, 1920, the Journal of the American Society of Mechanical Engineers. See also Engineering News-Records, issue of April 8, 1920, pages 710–712. The complete paper has been issued as Number 4 in the “Reprint” series of Engineering Foundation. Copies can be had by members on application to office of Engineering Foundation; non-members may obtain copies at the rate of 35 cents each.
