The filtrate flow rate in constant pressure filtration___________________?
Correct answer: B. Continuously decreases
- A. Continuously increases
- B. Continuously decreases
- C. Remain constant throughout
- D. May increase or decrease; depends on the pressure
Explanation
At constant pressure, the growing filter cake adds resistance to flow as filtration proceeds, so the filtrate flow rate continuously decreases. The pressure remains fixed, but the hydraulic resistance does not.
