摘要

The present paper provides an experimental method of finding simultaneously the pressure and the flow rate, and accordingly the hydraulic impedance, at any section of a pipe having a pulsating oil flow, from the pressure data detected at two fixed points separated by only a few hundred millimeters along the pipe, describing its theoretical basis, the experimental verifications and the procedure for practical use. The method is actually a modification of the kinetic differential pressure (KDP in acronym) method which one of the present authors developed to measure transient flow rates in oil hydraulic lines. Through measurements of impedances for a pipe with its end closed and also for a Helmholtz resonator usually used for pulsation reduction, the method has proved to be a reliable and convenient experimental tool.
