Flow of filtrate through the cake in a plate and frame filter press is best described by the ______________ equation?
Correct answer: A. Kozeny-Carman
- A. Kozeny-Carman
- B. Hagen-Poiseuille's
- C. Fanning's
- D. Kremser
Explanation
Flow through a porous filter cake is described using the Kozeny-Carman relationship, which relates resistance to cake porosity, particle size, and cake thickness. Hagen-Poiseuille applies to ideal flow through individual capillary tubes.
