find the speed of sound (in m/s) at -35°C at 1 atm pressure in dry air
physics please help! - drwls, Sunday, April 15, 2012 at 7:34pm
There are many websites online provide the speed of sound in air as a function of temperature.
Try this one:
The most accurate formula is
Speed of sound = sqrt[(gamma)*R*T]
where T is the Kelvin temperatuere and gamma is the specific heat ratio, which is 1.4 for dry air. R' is the molar gas constant divided by the molecular weight of air .
