Which of the following represents the plot of filtrate volume versus time for constant pressure filtration ?
Correct answer: A. Parabola
- A. Parabola
- B. Straight line
- C. Hyperbola
- D. Exponential curve
Explanation
At constant pressure, cake resistance increases as filtrate accumulates, giving the conventional parabolic filtration curve rather than a straight-line volume-time relation. A straight line is associated with constant filtration resistance.
