Description
図6は、試験装置100の断面図である。図7は、図6の試験装置100による揚水試験の結果を示すグラフである。試験装置100は、揚水管101と、給気管102と、図示しない空気源であるエアーポンプと、図示しないエアーポンプの電源である太陽光発電システムと、水槽103とで構成されている。
全長が6m、内径が200mmの塩化ビニル製の揚水管を海中に設置し、内径が18mmの給気管を揚水管の上端から挿入し、給気口の海面からの深さが4mの位置において、揚水管内に0.2MPaの圧力で空気を供給し、揚水された海水を容量が13Lのバケツで受け、バケツが一杯になるまでの時間を3回計測し、3回の平均揚水速度を算出した結果、揚水速度は160L/min(9.6m3/hr)であった。
全長が6m、内径が125mmの塩化ビニル製の揚水管を海中に設置し、内径が13mmの給気管を揚水管の上端から挿入し、給気口の海面からの深さが1m、2m、4mの位置において、揚水管内に約0.13〜0.15MPaの圧力で空気を供給し、揚水された海水を容量が13Lのバケツで受け、バケツが一杯になるまでの時間を計測し、揚水速度を算出した。揚水時の海水温度を表2、揚水速度の算出結果を表3に示す。なお揚水時の外気温は30.5℃であり、天候は晴れであった。
