How is sand measured

WebThe permeability of a core sample measured by flowing air is always greater than the permeability obtained when a liquid is the flowing fluid. Klinkenberg (1941) postulated, on the basis of his laboratory experiments, that liquids had a zero velocity at the sand grain surface, while gases exhibited some finite velocity at the sand grain surface. WebWhile two DFT measurements might be expected to be very close, two surface profile measurements can differ considerably. Such is the nature of a blasted surface. For example, on a panel blasted with a mixture of coarse and fine staurolite sands, replica tape measurements ranged between 1.8 and 2.9 mils, stylus instruments between 1.8 and …
