WebThe flow-ability of a powder is subject to the aggregate effects of multiple particle properties, interactions and environmental conditions. Shear cell measurements entail applying a range of load stresses to a powder bed and measuring the shear stress at the point of … WebA lot of work has been done to predict the apparent diffusion coefficient in porous media. Carman (1939) has shown that, in porous rock, fluids must move on the average at about 45° to the direction of flow (Figure 3‑5). Hence, when fluid has traveled a net distance, L, it has traveled an actual average distance of about √2 x L.
