Dimensions of the observation channel of the tank are 6 m in length, 2,2 m in width, 1,2 m in height. We divided the observation channel into five sections in the direction of flow. We made the center of the channel "section B", The following characteristics were clarified: 1) The current in this tank hardly changes against time and shows high stability. 2) The current of the central area of each section is widely uniform, even though the current near the wall is relatively faster and near the glass is slower. 3) There is no torsion of the flow. 4) The mean velocity (Vm) of section B is representative of the velocity at the central measurement point. 5) Vm is also calculated from the panel velocity (Vp), which is indicated on the panel, with the following expression. Vm = 1.075 ・ Vp - 0.64 6) The characteristics of the water tank are not influenced by temperature of 9~31℃. 7) There has been no marked temporal change of the characteristics of the water tank, at least over the last three years. 水産大学校 National Fisheries University 2006-03-20 eng departmental bulletin paper https://fra.repo.nii.ac.jp/records/2011815 fishu_k_54_31 https://agriknowledge.affrc.go.jp/RN/2010731276 agriknowledge AN00124678 0370-9361 水産大学校研究報告 Journal of National Fisheries University 54 2 12 31 42 https://fra.repo.nii.ac.jp/record/2011815/files/fishu_k_54_31.pdf application/pdf 1.7 MB 2024-10-11
