A steady$-$state flow test was conducted on a core sample $1$ inch in diameter and $2$ inch long.

The table below lists the total pressure drop, fluid flow rates and saturation data for each

step of the test. Compute and plot the effective permeability curves for this core and

estimate $S_{wi}$ and $S_{or}.$ Oil and water viscosities are $2\mathrm{.}5cp$ and $1\mathrm{.}1cp,$ respectively.
