Abstract: | Methods for calculating constant terminal-settling velocities (vs)of spheres are examined for their validity and limitations of usefulness. A different approach is given which accurately predicts vs
for spheres over a wide range of hydraulic conditions based on past experimental work. The theory behind this approach is given along with the listing of a
fortran
program which directs the calculations of vs.The practical limits of the author's method are stated, and tables of vs
may be generated from the program for common mineral densities over a range of sizes useful to sedimentologists. |
