This plot shows the static pressure in psi along the upper and lower walls of the duct as a function of axial distance x in inches. Along the lower boundary, the pressure starts out just below 10 psi at the inlet (at x = 0), stays constant until about x = 1, then gradually increases to its final value of 14.13 psi at the exit. The pressure along the upper boundary is basically the same as along the lower boundary, except that it dips down to about 8 psi in the region of the expansion corner at x = 2, and increases slightly above its exit value at the compression corner at x = 6.
