Abstract


This work presents the results of a laboratory study aims to improve the inlet of the pipe syphon to decrease the head losses resulting from the sudden contraction in the pipe. Box-type wing walls are considered upstream and downstream. Theoretical and experimental studies were conducted. For experimental study models with different cutting angles, measured from vertical axis, of pipe inlet (1= 0 O, 15O, 30O, 45 O, and 60O). The pipe syphon was tested under different discharges (Q = 7.28 to 57.20 lit./sec). Different downstream submergence ratios (Hd /D = 0.0, 0.25, 0.50, 0.75, and 1.0) were considered. Dimensional analysis is employed to get the relationships between the different factors affecting the head losses through the syphon. The results of the study led to practical recommendations that are useful in the design of syphon inlet with low head losses.
