7b Method 1 Apply the integrated form of Darcy’s Law to the core before it was cut. Apply Darcy’s Law to each piece after the core has been cut into N equal pieces. 7b Method 2 The total permeability of the core is the harmonic average of the permeabilities of the pieces in series. 8b To generate the calibration curve, use the given data to plot a graph of Vs vs P1/P2. This should be a straight line. It is always advantageous to plot a linear calibration curve if possible. 1 shows the calibration curve.
