Speed of Sound in Gases, Fluids and Solids The acoustic velocity can alternatively be expressed with Hook's Law as c = (K / ρ)1/2 (2) where K = Bulk Modulus of Elasticity (Pa, psi) ρ = density (kg/m3, lb/ft3) This equation is valid for liquids, solids and gases. The sou...
EQUATION OF STATEThe speed of sound in liquid sulfur hexafluoride has been measured along isotherms at temperatures from 230 K (close to the triple point) to 333 K (above the critical temperature) at pressures from near saturation to 60 MPa. The measurements were carried out using a pulse-...
The speed of sound equation is expressed as, Speed of sound = The square root of (the coefficient ratio of specific heats × the pressure of the gas / the density of the medium). Speed of sound = \[\frac{\text{(the coefficient ratio of specific heats} \times {\text{ the pressure o...
Assuming the air is at a standstill, the speed of the sound wave through air can be calculated using the following equation, where Tc is the air temperature in Celsius. If the air is moving, the speed of sound will change depending on the direction of air movement. For example, if the...
The speed of sound in an ideal gas can be determined using the following equation: , where Vs- speed of sound, R - universal gas constant (8.314 J/(mol K)), T - absolute temperature (in Kelvin), M - molecular mass of the gas (in kg/mol), γ - adiabatic constant of the gas. ...

So whatever we do, increasing the temperature increases the speed of sound, but it does it in different ways depending on how we let the gas expand as it's heated. Just as a footnote, an ideal gas obeys the equation of state:
Distance is the distance traveled by the ping, time is how long it took the ping to travel to the target and return. With this we can rearrange the equation to solve for rate, which would be the speed of sound: rate = time/distance ...
The heart of the OPM is the binary gas analyzer BGA244. It determines the speed of sound of a continuous gas stream by measuring the resonance frequencies inside a cylindrical resonator cell. A wideband acoustic signal is injected into the cell by a speaker and the transfer function is ...
