Nope. Energy of wind goes like v^2. So, Patricia's 200 mph winds are about twice as damaging as Hurricane Andrew's 165 mph winds. 200mph winds are enough to strip bark off trees that remain standing.

I quoted energy. You're giving a power (energy per unit time).

Right, but my initial message didn't specify what the cubic factor was for. Didn't say energy, just that it was there in considering wind and water currents. (But, if you look at energy flow across a cross section, that *does* increase with a cubic factor.)
But that's not really the point. What does that mean in regards the destructive potential of a wind/current, and how it scales with speed?
I can only vaguely remember what I remember reading. Something to the effect that water currents are much more dangerous at higher speeds than might be expected. A caution to folks who have to deal with a current.
This seems like the sort of thing that would be covered in an engineering course; was hoping that someone could provide more in depth information.
As an example of how this is important, an increase from 175 to 200 mph represents either a 30% increase (square factor) or a 50% increase (cube factor).
Thx!

The current I am most likely to run afoul of is electrical current. Not much needed to stop a person. Of course the Velocity of electrons are a bit higher then hurricane wind Velocity being at C
