The drag coefficient of a plane net pulled parallel to the direction of motion was estimated. Results obtained are summarized as follows: 1) The drag coefficient, D8 of the plane net pulled parallel to the direction of movement is formularized; the parameters of which were determined by the least square method using the experimental results and is as derived from the following equation. D8=0.37(D/L)-0.58(D/L)3/2. where D is the diameter of a twine, and L is the length of a bar. 2) The drag of plane net pulled parallel to the direction of movement is reduced due to the wakes formed behind the bars.
