Answer: D. based on separation of particles on size
Comments: Centrifugation is the technique used for the separation of particles in solution based on specific characteristic of particles like; size, shape, density, viscosity etc. There are different types of centrifugation
- Density gradient centrifugation : Two different types 1) Rate-zonal centrifugation and 2) Isopynic centrifugation
- Differential centrifugation
- Ultra centrifugation
The rate–zonal centrifugation: In this technique of centrifugation the suspended particles separated based on their size.

Particles having size of 0.1mm, a shape factor of 0.8 and a density of 1650 kg/m' are to be fluidized using air at 25°C (p=2.374 SI, u=1.45x10ʻSI) and 202.65kPa (abs pressure). The bed's height at minimum fluidizing conditions is Lmf=1.6m. The bed diameter is 0.5m and the bed height when the particles are at rest is Lo=1m. 3.1. What is the mass of particles to be used ? 3.2. Calculate the minimum void fraction of the fluidized bed? 3.3. Calculate...

A sedimentation tank is used for the settling of a suspension of uniform particles of glass in liquid water. It was found that the relation between the observed sedimentation velocity of particles Uc and the fractional volumetric concertation of particles C is given by the following equation: uc u -=(1-C) 4.8 where U, is the free settling velocity of an individual solid particle. Note that the volumetric rate of sedimentation (settling) per unit area or flux is equal to the...
