A)
A homogeneous core has a radius of 2.0 cm and a length of 1.0 m. It is placed
horizontally. The permeability of the core is determined by flooding the core with pure
water of viscosity 1.0 cp, applying a pressure gradient of 0.5 bar over the length of

We can consider the two compartments as a static fluid system which is only forced by gravity. It is
obvious that when capillary pressure is zero and free water level seats at the same vertical depth with
