Gas Flow Velocity
Gas Flow Velocity
(OP)
Can someone run down the principles of gas flow velocity? I was under the impression that heated gas accelerates as it moves through piping around curves.
I do computers, and I have been trying to expand on some of the latest technologies with heat transfer for components using pipes filled with various gases to carry heat from the source to a external location for cooling.

RE: Gas Flow Velocity
so velocity = mass per time / density = (lb per time)/ (lb/cf) = cubic feet per time.
linear velocity is velocity / area of tube cubic feet per time / square feet = feet per time.
If the density gets lower because its hotter, then the velocity must increase.
so yes, the fluid will accelerate. as it heats up in a tube.
As for around bends, the only reason the (average) velocity would increase if 1) the fluid got hotter in the bend, or 2) the bends area got smaller.
