Sounds waves in a pipe of varying cross-section are described by the equation
V2 d/dx (1/A dAu/dx) = d2u/dt2
Where A = 0.2+0.3x
So first I substituted A into the equation:
V2 d/dx (1/(0.2+0.3x) d(0.2+0.3x)u/dx) = d2u/dt2
V2 d/dx (0.3u/(0.2+0.3x) du/dx) = d2u/dt2This is as far as I can get, any help would be fantastic.
