libs.performance_tools.standard_atmosphere.sound_speed(t=288.15, h=-1)

Compute the sound speed in m/s at a given temperature in Kelvin or altitude in feet

Parameters:

• t – temperature (K)

• h – altitude (ft) (if h is given then temperature is not used)

Returns:

air speed (m/s)

Return type:

a

Example of use:

t = 270 a = sound_speed(t)

h = 34000 a = sound_speed(h=h)
