You guy are about a million times smarter than I, but I got a
question
wrong on a test years ago and it nags at me.
What would seem to be the more destructive force.
High pressure water or:
Massive water flow. IE volume
I guessed volume but it was wrong but I think the test was wrong.
It wasa long time ago and before I croak I need somee finality on
this.



In school I used to like to call these "what am I thinking" questions.
I am assuming the question might have had more detail, but possibly
not. But let me put it this way; If the energy in the high volume/low
pressure river is harnessed it can likely power 10 high pressure low
volume water jet cutters. Or one could approach the question as "what
do you mean destructive force? cutting a canyon out of rock and sand
over a few thousand years or cutting a .125 thick titanium plate in 10
seconds.

The next question is whether the question is asking for force or
power. If I have a tight lug nut on a wheel and I tie a 100 lb weight
on a 1 foot wrench I can exert a FORCE of 100ft/lbs of torque for 3
months, but there is no POWER transmission without movement.

Hope that helps
