 note = {Field experiments were discussed in previous reports, this time authors plan to discuss on the gear efficiency of sea slater net, basing on the physical characters of net. Authors carried out
model experiments and investigated them, comparing physical charcter of ordinary net with that
of sea slater net. Results obtained in this study are summarized as follows;
(1) In ordinary towing condition, height of two types of net were 3.2~2.3 m on ordinary
net and 3.4~2.4 m on sea slater net respectively. Gap-height of sea slater net was about 10% less than that of ordinary net. And then the fact estimated that it originated that the friction
of bottom could be neglected on the experiment in the circular tank.
(2) The following were obtained as an empirical equation within the limts of this experiment.
The example shows the case of 7.6 m of wing distance.
Height of net mouth ･･･[the rest omitted], (1) 網口高さは通常曳網状態で普通網3.2~2.3m,離底曳き網3.4~2.3mと略同じ値を示すが離底高さを考えた網口開口部高さは普通網が約10%少ない。これは模型実験では接地摩
擦抵抗を無視せざるをえないことに起因すると考えられる。
(2) 網にかかる流水抵抗は両網とも略同じである。いずれの場合でも抵抗の一般式R=kV^<n>として表わされるが,離底曳き網ではnの値は小さく網口形状の変形が大きい。(3) 垂下チエンの形状を単位長さに働く力として平行な力,垂直な力及び重力の釣り合いと考えて近似した結果実験値は計算値と略一致した。},
