Can we really compare the fluids here?  Does air react the same as water
under these conditions?

It does under most conditions. Flow rates and RPM's are different of

course.

Water tunnels are frequently used to visualize aerodynamic flows.
I think we had a big discussion on this awhile back.

Yes we did, just wasn't sure that discussion would apply to pumps.  What are
the forces behind cavitations, or is it even worth discussing?

I am not sure I understand the question.

BTW this is the best dissertation on what happens inside a cooling jacket I
have seen so far. It is from Heisler's book Advanced Engine Tech.

As you can see it is very important to carry off any unstable film boiling
with increased coolant flow.
