Question 3.iii

Constant rate filtration - filtration rate was 4.6x10^-6 m³s^-1

The same quantity of a similar suspension to problem 2 was filtered on the same filter at constant rate until 2.3 litres of filtrate had been recovered.

The time taken to achieve the filtration to this stage was (s):

	a) 678 b) 6287 c) 24 d) 500
In a constant rate filtration pressure increases linearly with time, or filtrate volume.
