Question 3.v

Constant rate filtration


The following empirical equation for pressure was observed

constant rate filtration equation for pressure

and the general filtration equation is: general filtration equation

Assume an incompressible filtration: i.e. alpha, c as well as A and viscosity were unchanged from question 2.


The medium resistance was (m-1):

  a) 6.2x1010
b) 5.7x1011
c) 2.2x109
d) 4.5x1010
In a constant rate filtration pressure increases linearly with time, or filtrate volume.
