Are you saying hoses do not themselves lose (waste, consume, dissipate,
whatever) power?

That's the gist of it. If you have a small hose, you cannot
support a large flow to run, say, a large impact wrench.
The same as trying to fill your washing machine through
a piece of 1/8 inch diamteter copper line. It will just
take a long time.

But the small piece of copper line does not dissipate
energy when doing so.
