如何計算理想氣體的音速

 

How to calculate the sound velocity for an ideal gas

The following formula can be used to calculate the speed of sound in an ideal gas :

With :

a = speed of sound in m/s
k = specific heat ratio or isentropic coefficient
R = perfect gas constant = 8314
T = gas temperature in K
M = molecular weight in g/mol
