Answer:
Velocity in air is given as :
V(air) = (yP/r)
Where we have :
P = Atmospheric pressure at Ntp which is given as :
101325 pascals
Y = Gamma
r = The density of air at NTP.
In this case we have been given all the parameters as follows.
Y = 1.4
r = 1.29 kg/m^3
We do the substitution as follows :
V(air) = {(1.4 × 101325) / (1.29)}^1/2
V(air) = (109965.1163)^1/2
Getting the square root we have :
V(air) = 331.61 m/s
