The speed of sound in mph can be calculated using the formula: v = \sqrt {\frac {\gamma \cdot P} {\rho}} v = ργ⋅P. Where: v = Speed of sound. γ = Heat capacity ratio of the medium (approximately 1.4 for air) P = Pressure of the medium. ρ = Density of the medium. Speed of Sound In Water:
Speed of sound - Wikipedia. An F/A-18 Hornet displaying rare localized condensation at the speed of sound. The speed of sound is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. More simply, the speed of sound is how fast vibrations travel.
At normal atmospheric pressure, the temperature dependence of the speed of a sound wave through dry air is approximated by the following equation: v = 331 m/s + (0.6 m/s/C)•T where T is the temperature of the air in degrees Celsius.
The calculators below can be used to estimate the speed of sound in air at temperatures close to 273.15 K (0oC, 32oF). Speed of Sound - SI Units. k - ratio of specific heats. R - individual gas constant (J/kg K) T - absolute temperature (K) Speed of Sound - Imperial Units. k - ratio of specific heats. R - individual gas constant (ft lb/slug oR)
