Flow Through Porous Media

    • Homework posted in wrong forum, so no template
    I've never done a question similar to this one, and I've found myself stuck on it for a while now. I was hoping for some guidance on where to begin, because I truly have no idea:

    An incompressible fluid flows through a porous cylindrical shell with inner and outer radii R1 and R2, respectively under steady state conditions. At these surfaces, the pressures are known to be p1 and p2 respectively. The length of the cylindrical shell is h.
    (See diagram)

    Find:
    A) Pressure distribution
    B) Radial flow velocity
    C) Mass flowrate

    (Hint: For the flow of a steady state incompressible fluid through porous media, the equations of continuity in the cylindrical coordinates (r,Θ,z) are expressed by d/dr(rq) = 0 in which q is the Darcy velocity).

    You should also be warned for no effort. Please write down Darcy's law in cylindrical coordinates for a purely radial flow.
