| Summary: | (3.56 - 8.67), rolling on an impermeable, flat bottom under 0.52 m) were steady and uniform in velocity except near the 1 15 m), specific gravities (1.57 - 3.17) and aspect ratios above a superthreshold current velocity, the ratio of the are almost independent of specific gravity. The measurements below 0.70. However, the threshold and superthreshold bottom and the side walls. A video processing method was currents in the flume of a uniform cross section (0.47 m x currents of velocities ranging from 0.3 m/s to 1.0 m/s. The cylinders as a function of time. The experimental error cylinders shows that the cylinders do not roll with pure developed to document the linear and angular positions of the diameter, aspect ratio and blockage ratio when the current encountered due to video resolution was studied and minimized Experimental studies were conducted to measure the motion of gravity. Analysis of angular and linear motion of the increase in current velocity. When the current velocity is radius of the cylinder is greater than average linear center rotation. Both steel and PVC cylinders experience back- show that the relative terminal velocities of cylinders with slightly above 0.70, while those of cylinders with large slipping, where average angular velocity multiplied by the small specific gravities (1.57-1.71) range from 0.70-0.72, specific gravities (2.77-3.17) range from 0.64-0.66, slightly terminal velocity to the current velocity (relative terminal the current velocity is greater than the superthreshold through the use of a proper data sampling rate The terminal unrestrained cylinders with different diameters (0.048 m - 0. velocities are smaller for a cylinder with smaller specific velocities of the cylinders are found to be independent of velocities of the cylinders are found to increase with an velocity in the x-direction. velocity is greater than the superthreshold velocity. When velocity, the relative terminal velocities of the cylinders velocity) seems to be around 0.70. The relative terminal |
