Since the water pump needs 10 HP to _operate_, and the pump
is indeed operating (as indicated by the pumping of water), then
wouldn't the output power of Newman's motor be at least
20 watts + 7,460 watts?

No.

The problem is that the number "10 HP" was pulled out of context. It was stated as though it's an absolute, black-and-white thing -- if the value is less than this, then they would have us believe that the pump /won't/ /go/, won't operate at all.

That's absurd, and it's certainly false. And it's confusing, which is the reason JNP quoted it that way, no doubt.

The pump is specified, by its manufacturer, to provide a particular level of performance. (We don't know what that level is; JNP isn't saying.) The pump is specified by its manufacturer to require drive from a 10 HP engine in order to achieve its rated performance.

There is no guarantee by the manufacturer that the pump will not pump /at/ /all/ unless the drive motor is at least 10 HP!! But that is exactly what JNP wants us to believe.

For the 10 HP figure to mean /anything/ we would need to know:

* What rate the pump will operate at with a 10 HP motor connected to it. (This value could surely be found in the pump owner's manual.)

* What rate the pump is operating at when the JNP engine is connected to it.

They won't tell us either of those things.

FWIW, as a point of reference, a 10 HP motor driving a reasonable pump should produce an output stream that looks a lot like the water coming out of a firehose. That's a very heavy-duty rig.

*********************************************

Look at it differently.

The motor requires 20 watts of input electrical power.

The insinuation that it's producing 10 HP implies that the output is over 300 times larger than the input -- and the output is in the form of straight mechanical energy, which is very easy to utilize.

Connect the motor to a generator, rather than the pump. With a factor of THREE HUNDRED to play with, it's just false to claim the loop couldn't be closed with that rig, IF it performed as they would have us believe.

Yet they can't close the loop!

Ergo, it's /NOT/ producing 10 HP of output power.

I would love to put a benign interpretation on their actions, and see the glass as being at least half full, but I can't see any such interpretation which makes sense.
