Drill Solids Settling Velocity

This model requires very little data in and is very easy to use. All that needs to be known is the 3RPM, 100 RPM and the mud weight. The specific gravity and particle size can be estimated as that of sand accordingly. The model uses an iterative approach to solve 3 equations with 3 unknowns and the convergence is fast in two iterations generally. The method is from API Recommended Practice 13D, Third Addition, June 1, 1995.
