摘要

Locating a cod type net, provided with extremely small sized mesh like a plankton net, in the running water, it is assumed that, owing to the so-called "Submerged Orifice" of the mesh, comparing to the current speed outside the net the one inside decreases; then the static pressure inside the net increases and the water current, having speed in proportion to the square root of the difference between the outside pressure and the inside one, passes through the mesh of the net. As shown in Fig. 1, it is also assumed that the plankton net is made of only net I
