Determination of the settling velocity Vertically falling body in liquid using specimens of different sizes and different materials Features - settling velocity of spheres of various diameters and densities Learning objectives/experiments - influence of the following parameters on the settling velocity of spheres: -- diameter of the sphere -- density of the sphere -- density of the fluid -- viscosity of the fluid Specification [1] experimental unit to determine the settling velocity of different spheres [2] 2 transparent cylinders [3] marking of the measuring section [4] cover with guide tube to insert the sphere [5] sluice to remove the spheres from the cylinder [6] 10 spheres of various densities and diameters [7] 2 areometers to determine the density of the fluids [8] stopwatch to measure the sedimentation time Technical data 2 cylinders - inner Ø: 92mm each - height: 1330mm each - sink height: 1000mm each Spheres - aluminium (density: 2,7kg/dm3) -- 2x 5mm Ø -- 2x 10mm Ø - polyoxymethylene (POM), density: 1,41kg/dm3 -- 2x 5mm Ø -- 2x 10mm Ø - polyamide (PA), density: 1,13kg/dm3 -- 2x 10mm Ø Measuring ranges - density: 1x 0,8...1,0kg/dm3, 1x 1,0...1,2kg/dm3 LxWxH: 720x640x1650mm Weight: approx. 45kg
