Abstract: Through the experimental research of the brine-the water eyelet periodic aerial drainage and the measure of the length of 8 different holes which is 1.32 mm aperture, we obtain the cycle in proportion to the length of the hole 1.1 ±0.1 powers of exponent. At the same time, we track the record of the inner tube liquid level which has 1.32 mm aperture and 113.00 mm length to get the experimental curve which is the exponential form, this is in good agreement with the theoretical analysis.

Key words: salt water-water, discharge, index, hole length, surface location
