from results computed from Formula II. 
senting the data in tabular form. The logarithmic scale, which is 
used for all the diagrams, simplifies the plotting and increases the 
legibility for small differences in head. To illustrate the use of the 
_ djagrams in finding the discharge, assume a 3-foot flume with a 2 by
