What would happen to a 60 MPH wind that entered a rudimentary funnel of some 4 meters in length via an entrance of say 1 square meter and exited through an exit of maybe .25 square meters? I'm interested in what happens to the pressure, speed, and the force of the wind as well as how much wind simply bypasses the structure. Also, I'd like to know if there is something approaching an ideal ratio of entrance area, to exit area, to length for maximum output force. Any other info or useful formulas for compressible fluids would be greatly appreciated.
