| 内容記述 | In the investigation of marine phenomena on a bay or an inshore in where water temperature, salinity and etc. are changing with the tide, an instant sampling water by reversing bottle may be able to show the only datum on one point at that instant. The datum is not always a typical value in the point. Then, many data by oftentimes sampling are needed to get the average value correctly. The authors projected the appartus to sample sea-water continuously for long time (12~36 hours) by means of laminar flow in a capillary. When, in Fig. 2, H (cm) is pressure head ; l (cm), length of capillary ; d (cm), inner diameter of the one ; ν (cm^2/s), kinematic viscosity of sea water ; Q (cm^3/s), sampled volume ; then |

| 内容記述 | Using d=0.050~0.125cm and l=5~15cm, Q (cc/s) against H (cm) is shown in Fig. 1. To sample approx. 500cc of sea-water per day by d=0.05cm, it is known from this figure that l=5~10cm and H=3~7cm must be used. Under the theoretical condideration, they examined various types of water bottle for the utility of this idea. The results of experiments with (I)-type and(III)-type (in Fig. 3) are shown in Fig. 4 and 5 respectively. It was very difficult to adjust the pressure in the bottle for a regular sampling. Because the apparatus was set up and dowm in rough sea, sea-water had been poured into the bottle through an air out-let (bubbling) pipe. Then, water sampling was dammaged by the contamination of unexpected water. On the purpose of checking the reliability of this apparatus, the calibrating test was carried on with (IV)-type (in Fig. 3) in the sea-water tank (salinity was changed artificially). The result of this test was shown in Fig. 6. The authors finished the experiment of continuous sampling with (V)-type in the tank. The last apparatus (bubbleless water bottle) can be used even in rough sea, and, in spite of the decreasing of H (cm, head), this bottle will be the most useful in the point of its reliability. |
