I'll answer jtroutma...
There is a point in electrical current where the amperage is so high, that it restricts the current.
Similarly, there is a point where the coolant speed is so high, that the pressure buildup increases to restrict flow.
That aside, the analogy stands. If you want to be picky, I'll throw this in: 60 volts @ 50 amps, versus 50 volts @ 60 amps. Both are 3000 watts.
