Terminal velocity formula for spheres in a viscous fluid

Various attempts have been made to develop a general expression for the terminal velocity of spheres in a viscous fluid (Stokes, Prandtl, Oseen, Rubey, etc.: see Bogardi, 1974 and Vanoni, 1975). All of these formulae show a lack of accuracy and/or are restrict ed to a relatively small range of Reynolds numbers. Since sieving is a time consuming...

An improved settling tube system

In this report a settling tube system is described for the measurement of the settling velocity distribution of sand samples with particle diameters ranging from 0.1 to 2 mm and sample weights ranging from 0.1 to 20 gf(10^-3 to 0.2 N). The time of arrival of the particles is detected by means of an underwater balance. The response, stability and...

Settling Tube Analysis of Sand

For various reasons particle-size analysis of sediment is used in many fields of science and technology, a.o. earth sciences, agricultural and civil engineering. Relatively coarse-grained sediment like sand, with dimensions ranging from 0.06 till 2 mm, is analyzed almost exclusively by sieving. The size of particles in the silt and clay range (0...
