Generally understood. I redid everything, cut out the area in a different way. Added moment of inertia.

Everyone thinks everything is in order, BUT.

My wheel spins water from two circuits (inside and outside), when the volume is removed from a solid body, a void remains between the shoulder blades, and the fluent separates these two areas into two bodies, respectively, and turns them differently. How to connect them? For the fluent to see it as one body?

I will create a new topic.

This one can be closed.
