Develop an expression for the ratio of orthokinetic and perikinetic flocculation rates for a monodisperse suspension
a. What is the ratio of orthokinetic to perikinetic flocculation for a particle of diameter 100 nm (0.1 um)? (the typical size of a virus).
b. For d=1 um (the typical size of a bacteria)
c. For d=10 um (the typical size of a protozoean oocyst)
Please explain!
