Consider the following pipe assembly containing a permeable filter of length L=20cm, area A=20cm^2, and permeability of 4 millidarcys. An incompressible fluid of viscosity=2 centipoise flows through this system due to a pressure difference of 1470 psia.
a) what is the volume flow rate of the fluid through the filter sections?
b) what is the velocity of the flow through the filter section?
c) How long will it take the molecule to pass through the filter section? show steps please and thanks.
