Pressure drop across conventional and diverging-converging pipe bends in the flow of multi-sized particulate slurries

Pressure drop across a conventional long radius pipe bend and two wear resistive pipe bends have been presented for the flow of multi-sized particulate suspensions. Measurements have been made over a wide range of flow velocities and solid concentrations. The study has shown that diverging-converging pipe bend has marginally higher pressure drop but exhibit a much longer life. Quantitative data on relative pressure drop and bend loss coefficient for the three pipe bends are presented and analyzed.
