Remember to take into account the vena cava
flow.

ROFL. Sure Paul. I did not know you studied medicine :)
Your not serous. (you're, a contraction that means you are)

The propeller flow is deemed vena cava, which means it starts out larger in
diameter than the prop disc, contracts as it flows into the prop disc, then
continues to contract and pick up velocity as it goes to the rear. At a
point many diameters behind the prop, the delta v is twice as much as at the
prop disc. That's the delta v you have to use in calculating thrust
horspower.
