In order to obtain sound velocity in liquid, an experimental method of measuring sound velocity is designed. A time-difference type ultrasonic flowmeter and normal flow checkout equipment are used to measure the flow speed of liquid in closed hydraulic pipeline simultaneously, then the measured value and the true value of the flow rate are measured, and the meter-factor of the ultrasonic flowmeter is determined. Furthermore, the relationship between the sound velocity and the meter-factor is derived under a certain condition. Based on the method, the velocity of sound in dinitrogen tetroxide (N2O4) at 7.6-19.4 ℃ and unsymmetric dimethyl hydrazine ((CH3)2NNH2) at 6.5-25.2 ℃ are measured at 0.17 MPa. It provides reference for measuring the sound velocity in other liquid.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
