wayne, are you really saying that while Feynman was right regarding the forces
involved in water flow, he wasn't right when water flowed over a rudder?

Interesting. Should you be able to show that you can beat sher to the next
Nobel prize in physics. Hurry.

Time to give it up Jax, you're busted.

Fact is Feynman was right, BUT,

[Sprinkler Heads] [not equal] [Rudders]

Prop flow over rudder in reverse is small but it's there.
