The inlet pressure in a constant rate filtration____________________?
Correct answer: C. Increases continuously
- A. Remains constant
- B. Decreases gradually
- C. Increases continuously
- D. None of these
Explanation
At a constant filtration rate, the cake becomes thicker and offers increasing resistance to flow, so the pressure difference and inlet pressure must rise continuously. A decreasing pressure is associated with constant-pressure filtration, not constant-rate filtration.
