Flow Velocity Downstream of Sound Wave Formula

Flow Velocity Downstream of Sound = sqrt(2*((Sound Speed Upstream^2-Sound Speed Downstream^2)/(Specific Heat Ratio-1)+Flow Velocity Upstream of Sound^2/2))
u2 = sqrt(2*((a1^2-a2^2)/(γ-1)+u1^2/2))

On what factors does the speed of sound depends?

The speed of sound in a medium is determined by a combination of the medium's rigidity (or compressibility in gases) and its density. The more rigid (or less compressible) the medium, the faster the speed of sound. The greater the density of a medium, the slower the speed of sound.
