5. Consider this figure below, which shows a 1D, single-phase, steady state flow taking place in homogeneous, porous medium. Use the diffusivity equation below and with the boundary conditions to find the pressure distribution function in this porous medium in its most general form (Hint: you may use Darcy's Law in the derivation).
