An investigat:ion has been carried out into the magnitude of energy losses that occur at a three pipe junction pit structure in a stormwater system. The investigation comprised basically of three parts:- a] A literature review. b] An experimental study. c] Analysis of the results. Over 100 tests were conducted on a model with a scale ratio of approximately 8:1. The tests were conducted over a range of flowrates, for each of these flowrates the upstream loss coefficient [ Ri^], lateral loss coefficient [ kj. ] and water surface elevation coefficient [ K^ ] were obtained. From the results of the experimental study it was possible to carry out a comparison and assessment of present literature and design data available.
