Abstract

An analytical model for the flow of spherical body in pipeline with density equal to that of water in laminar flow condition was obtained.A good agreement between the theoretical results obtained from the present work with that obtained from the literature.Results were obtained for the flow of spherical body in 0.03 mdiameter, sphere/pipe diameter ratio, k, corresponding to 0.6, 0.7 and 0.8.The average flow velocity varied from 0.036 to 0.073 m/s.Increasing the average flow velocity will increase the pressure gradient. Increasing sphere/pipe diameter ratio will increase the pressure gradient.
