I think the analogy holds up quite well, even though they don't go into the details that you mention. Losses in water transmission lines for example are also proportional to velocity squared.

Correlates well to how much current a given wire gauge can handle as well. If you hook the garden hose up to a fire hydrant and open it up, the garden hose might explode since it can't handle all the water. A pressure washer might use a thin hose, but the water sprays so hard that it can cut your skin. Idk, that's how I learned it growing up before I learned about stranded vs solid core wire, skin effect, resistance, etc.
