It is proper for us to make clear the fluid dynamic properties of the netting, by using a simplified net-models. For the purpose of this, it was planned to make the knotless plane net-models, using vinyl-chloride cylindrical-bar instead of netting twine. In this paper, some descriptions were made comparative experiments on netting materials consisting of the vinyl-chloride cylindrical-bar, and the cremona netting twine. The measurements were carried out with the hand-made equipment, which was capable of measuring simultaneously both the dragging component and the lifting component to be derived from the netting material, when they were set into the flowing water. The drag-coefficient C_D, the lift-coefficient C_L, and friction-coefficient C_F are to be calculated from the measured values of C_Dm and C_Lm as in the following formulae:- ・・・[the rest omitted]}, pages = {157--164}, title = {平面網地の流水抵抗に関する基礎的研究 I : 網地素材の比較実験}, volume = {26}, year = {} }
