2. Particle setting can be accelerated by a centrifuge that imparts a radial acceleration of w?r, where w is the rotation rate in rad/sec, r is the distance from the rotating axis. A centrifuge consists of a spinning region between the inner radius R; and the outer radius R., with a length L. Suspensions enter at one end and flow to the other end with solids collected on the outer surface. Ro RT L a. Assume uniform axial flow of the fluid. For a flow rate of Q, what is the expression for the mean fluid residence time? b. Explain this process in words, including the overall goal of the process.
