Jack,
I've been wondering about the reason for a constantly decreasing
crossection. Can you give a technical explanation why the taper
increases flow? Decreasing area means increasing velocity and
increasing kinetic energy. The pressure is also dropping, so the
density is dropping. It must be explained by the Bernoulli equation?
