Questions For Thinking And Discussing

1. We have an emulsion of oil in water that we need to separate. The oil droplets have a mean diameter of 10"4 m, and the specific gravity Of the oil is 0.91. Applying a sedimentation centrifuge to effect the separation at a spedd of 5,000 rpm, and assuming that the distance of a droplet to the axis of rotation is 0.1 m, determine the droplet's radial settling velocity.

2. Determine the settling velocity of a particle (d = 4 X 10"* m and pp = 900

kg/m3) through water in a sedimentation centrifuge operating at 4,000 rpm. The particle velocity is a function of distance from the axis of rotation, as shown by the following data:

Distance, m

Settling Velocity, m/sec

Reynolds Number
