The specific objective of this research was to determine the drag coefficient of a representative section of a water bed conveyor. This involved the investigation of the drag on a flexible membrane form in a confined open channel. Dimensional analysis was used as a basis for the design of the physical model of the water bed conveyor. The physical model was designed, constructed and installed within a flume. Testing of the physical model consisted of measuring the drag force on the Test Section and velocity distribution within the boundary layer developing along the Test Section. The measurements were undertaken while the Test Section was loaded with various quantities of different material types. The Test Section was fixed in the direction of flow by one load cell, while water was pumped through the flume at 25 l/s, 38 l/s and 63 l s. Momentum principle and the velocity data were used to calculate the drag force on the Test Section; this was then compared with the drag force recorded directly. The drag coefficient was calculated and comparisons were made to establish whether the tension in the membrane and/or the material type set-ups affected the drag coefficient.
