Maximum Thrust force in submarine

[ali nemati]

I am designing a submarine in low scale that the max propeller OD is 10 cm, means from center of shaft to propeller edge I have around 5 cm distance.
I am trying to find the maximum thrust as this submarine suppose to pull an object inside water pipe.
I need to find optimum rpm ,blade number and propeller design shape to create maximum thrust .
The water static pressure is suppose to be around 5000 PSI.

Many thanks for your feedback

This will depend on motor size/power and, more critically, prop geometry.

The water static pressure is suppose to be around 5000 PSI.

Is this a pipeline ?
