Example? Take a hairdryer and turn it on. Note the speed. Now block the flow completely. It speeds up! It wouldn't speed up unless the load was reduced.

Oops! Apples and oranges. The dryer example is only true because the medium is of variable density. Water can be considered (at least for this discussion) a medium of constant density. Here's the example- nudge your power boat bow-first up against the dock, then go full throttle. Note the max rpms. Then go out into the fishing channel where all the idiots in their row boats are, and go full throttle. Note max rpms. See?
