WebSpeed of sound in water, which is a liquid, is 1480 m/s. So, the speed of sound in the solids can be calculated as: v =√ (B/ρ) where, v → Speed of sound in the liquid. B → Bulk … WebBy definition, at Mach 1, the local flow velocity u is equal to the speed of sound. At Mach 0.65, u is 65% of the speed of sound (subsonic), and, at Mach 1.35, u is 35% faster than the speed of sound (supersonic). Why is Mach number useful? Mach number is an important quantity to compare the speed of any object with a speed of sound.
