METHOD OF DETERMINING LIQUID PHYSICAL PROPERTIES

摘要

FIELD: physics. ^ SUBSTANCE: gas is fed to the inlet of a gas-carrying pipe immersed at a given depth into the monitored liquid. Maximum pressure in the pipe is then measured. Repetition periods of gas bubbles are also measured at two different gas flow rates into the gas carrying pipe. Further, surface tension, density and viscosity of the monitored liquid are then determined from the value of maximum pressure in the pipe and repetition periods of gas bubbles. ^ EFFECT: higher accuracy of determining surface tension of liquid and broader functional capabilities of the method through possibility of determining density and viscosity of the liquid. ^ 1 dwg
