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. how to show text on screen in a script https://tlcperformance.org
