The results of measurement of the acoustic impedance of some viscoelastic fluids in circular tubes are presented. The fluids studied include water, petroleum oil, glycerol, silicone fluid, milling yellow solution, and agar solution, the last three showing elastic effects. One of these elastic effects is the changing of the acoustic reactance from the inertance type to the compliance type. Measured results are presented for frequencies from 3 cps to 300 cps and for tubes having radii in the range 0.0172 cm to 0.354 cm. Methods are presented for determination of the complex coefficient of shear viscosity from the acoustic impedance properties and examples are given.
