Includes bibliographical references: p. 46-49. "Approaches to design considerations of head losses at sewer junctions are examined. Such approaches include application of the momentum equation and the use of experimental pressure change and head loss coefficients which were reported in the literature. The latter approach, which seems to be both more accurate and practical, is recommended for sewer design. Literature data on pressure changes and head losses at sewer junctions are presented for straight-flow-through junctions, junctions with changes in the pipe alignment, junctions of a main and a lateral, and junctions of two opposed laterals. Other topics briefly discussed include head losses at Y-junctions and four-pipe junctions, considerations of junction head losses in pressurized sewer flow routing, and sulphide gas releases at sewer junctions"--Abstract, p. i.
