Web>Tbe velocity of sound in water containing air bubbles is very low. In pure water sound travels with a speed of 1500 m/s; this velocity decreases to 1OO m/s in water containing 1% by volume of air. The minimum occurs at 50% volume concentration at which a velocity of 20 m/s is observed. These equations were made using five major assumptions, with four of them being common to all the equations: 1. The bubble remains spherical 2. The bubble contents obey the ideal gas law 3. The internal pressure remains uniform throughout the bubble
