Calculate the Speed of Sound in Air vs. Temperature. The velocity of sound can be calculated in metric units as. v ms = 20.05 (273.16 + t C) 1/2 (1) where . v ms = velocity of sound (m/s) t C = temperature (°C) Velocity of sound in Imperial units: v fts = 49.03 (459.7 + t F) 1/2 (2) where . v fts = velocity of sound (ft/s)
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 20 °C (68 °F), the speed of sound in air is about 343 m/s (1,125 ft/s; 1,235 km/h; 767 mph; 667 kn), or 1 km in 2.91 s or one mile in 4.69 s.
25 Ιουλ 2024 · The formula for the speed of sound in ideal gases is: c = \sqrt {\frac {\gamma R T} {M}}, c = M γ RT, where: c c – Speed of sound in an ideal gas; R R – Molar gas constant, approximately 8.3145 J·mol −1 ·K −1; \gamma γ – Adiabatic index, approximately 1.4 for air; T T – Absolute temperature; and. M M – The molar mass of the gas.
the speed of sound is v sound = m/s = ft/s = mi/hr. It is interesting to compare this speed with the speed of molecules as a result of their thermal energy. For the specific example of dry air at 20°C, the speed of sound in air is 343 m/s, while the rms speed of air molecules is 502 m/s using a mean mass of air molecules of 29 amu.
Calculate the speed of sound (the sonic velocity) in gases, fluids or solids. A disturbance introduced in some point of a substance - solid or fluid - will propagate through the substance as a wave with a finite velocity.
