| 内容記述 | The flat-plate-frictional-resistance-tests executed in the Circulating Tank of Kagoshima University enabled the authors to have some formulas concerning the influences coming upon the flat plates from the wetted surface area, roughness of surface, and the fluctuations in water-temperature and the flowing velocity. In the present test, two kinds of flat plate models made of the Formosan cypress timber were used, which were of the same size as those used in Kyushu University, namely, the size of the one plate was 1 meter in length and 24 centi-meters in breadth, that of another was 1 meter in length and 9 centi-meters in breadth. The present test was resulted in our derivating an approximate formula which was close to Mr.K.E.Schoenherr's and Mr.G.Hughes's, hither to publicly acknowledged as the formulas having proper values. The formula begotten in the Circulating Tank seems to have been correcter than the one obtained in the towing tank. The quintessence of the testihg results are as described below:― The increasing contraction of the wetted surface area, the smoothing tendency of the surface roughness, the rising degree of the water-temperature and the lessening of the velocity of flowing water were ascertained to be matched by the decreasing fluid frictional resistance values. Through these experiments-co-relating with Reynold's number (R_n), frictional resistance co-efficient (C_f) and frictional Resistance (R_f) - such results as mentioned below were obtained and assorted in the formulas. ･･･[the rest omitted] |
