This volume in the Coulson and Richardson series in Chemical Engineering contains full worked solution for problems in Volume 1. This volume contains detail solutions for vol 1 questions.
It is found experimentally that the terminal settling velocity u0 of a spherical particle in a fluid is a function of the following quantities: particle diameter, d; buoyant weight of particle (weight of particle weight of displaced fluid), W; fluid density, and fluid viscosity, Obtain a relationship for u0 using dimensional analysis. Stokes established, from theoretical considerations, that for small particles which settle at very low velocities, the settling velocity is independent of the density of the fluid except in so far as this affects the buoyancy. Show that the settling velocity must then be inversely proportional to the viscosity of the fluid.
