The course starts with the characterization of particulate solids in respect of size, size distribution and size reduction. The fundamentals of motion of particles in fluids are covered to develop methods to calculate settling velocity of particles. The concepts of fluid flow and particle settling are used for design and operation of some of the important physical processes such as filtration, sedimentation, centrifugation and fluidization. The module is targeted at the third year part-time chemical engineering students working in the industry.\r\n\tParticle Size Analysis (MR Chapter 1)
