Is it possible to measure the thrust of a propeller under water whilst if 
is stationary? I think it has something to do the speed of the water in 
front of and behind the propeller, and also the speed the propeller is 
turning.  Is it possible to do this with propellers for model boats (of 
varing sizes), a small water tank, a basic motor powered by a basic power 
supply.

Thanks
