Develop Design Data On Pressure Loss Of Large Pipe Fittings, Patrick Dent

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pressure loss coefficients were determined for large radius ells, large concentric pipe reducers, and expansions, as well as large pipe tees. The fittings tested were 12, 16, 20, and 24 inch forged steel weld. Forty individual fittings from four different manufacturers were tested to determine loss coefficient values. Each test fitting was examined at a specified range of pipe velocities to determine mean and variation of loss coefficients. Tees were also examined for mean and variation of loss coefficients over a range of flow distributions.

Currently no data exists for pipe fittings of these larger diameters. This study will provide …
