چکیده انگلیسی
A diagram including five curves (for five durations) of distribution (or percent of drainage) vs. Pressure Duration were then plotted, each having a peak point, representing the average mean capillary pressure (Pcm.av) of the porous medium under study which is a measure of degree of homogeneity of the medium. Finally, it was shown that the CPD curve, indirectly, accounts for size distribution of the medium; hence, no need to calculate the PSD curve. Of course, simply, using CPD curve, the PSD curve as well as the average mean throat size (if drainage process) or pore size (if imbibition process) of the medium can be obtained using the general capillary pressure equation.
