Speed of Sound in Air
Calculate the speed of sound in air.
| Speed of Sound c | m/s |
| = | km/h |
At a temperature of 15 degrees, the speed of sound in air is approximately 340 m/s, and the speed of sound in helium gas is approximately 997 m/s.
Specific heat ratio k=1.403 (air)
Molecular weight M=28.966E-3 kg/mol (air)
Gas constant R=8.314462
Absolute temperature T=273.15+t °C
