Hello,

I'm a bit rusty with my fluid mechanics and can't seem to find the answer anywhere. Basically I have a pressure wave traveling in a liquid at the speed of sound through a pipe of the shape shown in the attachment (basically a semicircle of constant cross sectional area and then a cone of increasing area. At point A I know the wave has planar wavefront. Is there any formula to work out the shape of the wavefront at the end of the cone at point B, which I suppose will have a slight spherical curvature due to the changing cross-sectional size of the pipe?

Thanks
