  1. Example:Determine the settling velocity of solid spherical particles if the particle diameter is d = 30 pm and particle density is 1,950 kg/m3. The density of the liquid phase is 1,100 kg/m3 and its viscosity is 3.5 cp. Given that

  2. 1. Determine NRe

  3. 2. Calculate velocity from the following equation

  4. Water processing Mixing and flocculation Chemical reactors in water treatment are designed as either completely mixed or plug flow basins

  5. 1.1. Ideal completely mixed unit • The influent is immediately dispersed through out the volume, and the concentration of reagent in the effluent is equal to that in the mixing liquid. • for steady state conditions the first order reaction kinetics are given by • t=

  6. 1.2.Ideal plug –flow unit
