4. Liquid characterization measurements

4.1 Physical quantities

In the idealized case of a non-viscous fluid, in an infinite medium, D'Alembert's equation in its simplest form allows us to introduce the longitudinal ultrasonic velocity in the fluid: VL=1ρχ[AF3812] where χ is the compressibility coefficient. When ultrasound propagates in a real viscoelastic...
