hey-Hey!!!,
Y'all dissapoint me with your lack of interest in what is going on, and how it works in this stuff we use everyday. Failure to understand this stuff makes it hard to use any other shopping skill besides, 'I sawr it work real good fer him' when it is time for the next upgrade/improvement. How can one be sure you're not jus' getting a bottle of snake renderings? Allow me to link the wiki article on the Ideal Gas Law,
http://en.wikipedia.org/wiki/Ideal_gas_lawWhat I've done is some manipilation of pV=nRT ( see the article to define the constants ). With our IC's we wish to cool down a volume of compressed air. Actually it is a flow, but it gets treated as perhaps a moving volume...it doesn't make any difference. All this talk of large temperature drops with a good IC got me wondering, 'how much difference in density will it make with the numbers provided'? He went from ~450F to 160F...pretty damn fine to me. Soooo, back to the equation defining the Gas Law...what needs done with pV=nRT so it gives me the answer I want to calculate. We'll take a volume of air above the IC, it is at pressure_1(P1), volume_1(V1) and temperature_1(T1 ), and it will have the same number of air molecules once we pass it through the IC( assuming the boots aren't leaking ) and we then define its pressure, volume and temperature with 2's so the n is the same and we can remove R( algebraic slight-of-hand if you will, cancel it out, etc ). in any case the PV/T quantity both ahead and downstream of the IC is set equal to the same nR, so we can set p1*V1/T1=p2*V2/T2. I ignored pressure drop across the IC, and re-arranged to see how much volume changes after cooling from 450F to 160F( now look up a Farenheight to Kelvin temperature converter if you want a better number ), install the numbers and go...v2=v1*(T2/T1).
cheers,
Douglas
---don't mistake my suprised sarcasm for denigrating a *POSSIBLE* lack of education/understanding. There's all sorts of useful stuff, that when taken as an abstract concept is quite painful to learn and very boring. Doesn't mean one shouldn't make the effort. How thick does that bracket *HAVE* to be? What happens if the right answer is twice as thick as you built it? Is it somebody dead, or is it just a walk home instead of driving?
