First Generation Firebird-L Mailing List ......................................................................... Well said Joe!
I'm a Master electrician & Instrument technician and I don't believe I have heard it explained any better. But it is 14.696 psia or 101.325 kPa for us Canucks to be exact...(-; lol Brent Block 68 350 Coupe StAlbert, Alberta,Canada http://firstgenfirebird.org/show/closeup.mv?CarID=378 ........................................................................ . Ok, I'll explain. It's simple physics. Boyles law states that pressure and volume are inversely proportional. As volume decreases, pressure increases.... Take a full, open bottle of wine and flip it over to pour it out. You'll notice that it glugs. The air is rushing in to replace the liquid leaving the container. Remember atmospheric pressure is 14.7 psi and the inside of the bottle wants to have the same pressure as the outside. Now, do the same to a 2 liter of pepsi. You'll get the same glug BUT the container will also try to collapse. As the fluid leaves the container it is creating a void that the atmosphere is trying to fill and it is easier to collapse a plastic container than a glass one. The atmosphere does not know or care that the container is there, it just wants to fill that void. The same is true of buoyancy. But, we'll save that for the next science class. Now let's apply this theory to brakes. As you apply the pedal you are forcing fluid out of the reservoir into the line etc. there has to be atmosphere to replace the lost fluid. Yes, there are those rubber bellows that collapse down BUT the kicker is there has to atmosphere above them or they are working against a vacuum. joe ------------------------------------------------------------------------ Submissions to Firebird-L: <[email protected]> Unsubscribe from Firebird-L: <[email protected]> Help: <http://FirstGenFirebird.org/firebird/Firebird-L.html> Classifieds: <http://FirstGenFirebird.org/ubb/> Owner Pictures: <http://FirstGenFirebird.org/show/>
