Ultrasound Velocities

Acoustic Velocity (Sound Speed)

The sound speed in liquids can be measured using a pure sample of the continuous phase. The sound speed in a liquid can also be calculated if the mechanical properties are known. In this case:

Concentration Determination

The velocity of the sound wave through the slurry for a simple two Phase system
