| Abstract | This is a study of the hydraulic power losses in junction boxes
of storm drains , emphasizing the effect of the lateral spacing. The investigation was done in the laboratory. The experimental model of the study had the same configurations as that of Lorah, a previous investigator, who studied the power losses in a single junction box. The investigation was confined to the steady, uniform, sub
critical, combining flow of clean water. The angle of intersection
between the lateral and the main conduit was 90 degrees. Two positions of inlet condition of the lateral flow into the junction box were tested, i.e., the upper inlet and the lower inlet. There were three junction boxes in the model system. The spacings of the junction boxes were changed from 1 meter to 2 meters, 4 meters, 6 meters and 8 meters. The rates of the lateral flow into each junction box were kept the same. The effect of the spacing of lateral inflow on the power losses in junction boxes is identical. The results of the investigation were expressed in terms of some dimensionless power loss parameters and were presented in the forms of graphical relations with respect
to those parameters as well as in the forms of functional relations.
The results of. the investigation were compared with the results
obtained by Lorah. The agreements were reasonably close. |
