Using the wire net, the experiment was undertaken to obtain an empirical equation of the drag force that acts on the net when pulled parallel to the surface, while inclined to some extent, say an angle θ from the direction of motion. The results obtained are summarized as follows: 1) The relationship between the drag coefficients and φ could be expressed in the form of D8φ=0.45(D/L) tanφ-0.60{(D/L) tanφ}3/2, where φ is an angle of adjacent bars. 2) The velocity decrement due to the wakes have an effect on drag, but it has little or no effect on lift.
