Investigation of Liquid Leak Properties for Leak Inspection Technique Using a High Pressure Liquid

Abstract

Experimental and theoretical study of a liquid leak and gaseous a leak under high pressure was conducted in this paper. It is shown that the leak flow rate of the liquid increases in proportion to the pressure, and that of the gas increases square by the pressure in the leak path more than 1 micron in diameter and that increases in proportion to the pressure in the leak path less than 1 micron in diameter. And it is found that the liquid leak path transit time is within 0.1 seconds then it does not influence the inspection time.
