Hi,

I have a question that someone might be able to assist with - a
formula for - or an idea. I have a 12 inch x 10 inch 3 blade kaplan
prop for a bow thruster and I am trying to work out in rough handfuls
what power the prop will absorb at say 1500rpm.

Without doing the detailed calculations (because I'm feeling lazy tonight):
10-15 HP. Depends on blade area and tunnel fairing details but the number I
have quoted you is probably close enough for what you're thinking about.
