Experimental investigation in the permeability of methane …
Fig. 2 shows the particle size distribution of the fine quartz sands measured by laser particle size analyzer, Mastersizer 2000E, produced by Malvern Instrument Ltd. England. The volume weighted mean diameter was 36.695 μm, and the median diameter D(0.5) was 32.977 μm. The density of the fine quartz sands was 2.589 g/m 3, …
