Re: CFD - software

Don't ya just love trying to explain to people that things like 'suck'
and 'centrifical force' and such just don't exist?

It's "centrifugal", as in "centrifuge". And no, I don't
particularly.

This gives you about 30 inches of mercury or about 34 feet of water.
(Quick: what's the ratio of the density of mercury to the density of
water?)

Humm... using your figures, 2.5/34, or close to 1/14. Do you really
mean density, vs weight?

I asked for mercury/water, not water/mercury, but, yes, it's about
13.6. Of course I meant density. What's the weight of water?

Blowing the air faster doesn't change this.

Well, actually, it does. Not if the heat being introduced is more than
or even equal to the heat being removed. But passing more air (of a
lower temperature) over the hot spots will remove more heat from the hot
spots.

Blowing air around in the room matters, but the original statement
involved "removing warm air", not moving cold air.

A smaller temperature delta could exist. As the cooler air
takes on some heat, the faster it's replaced with more cooler air, the
more heat can be removed from the hot spots.

Huh?

As I said, I know from (bitter) experience how pointless physics
discussions tend to be in this forum.
