Just wondering if any of you out there know of any physic theories reguarding the properties of air when diferent variables come into play, ie CFM vs PSI vs Velocity,
I have some constants now but others may help.

 

i like phyics, but i don't really understand what you're doing....explain por favor

 

I really just want to learn more about the principles of air.... I'm ok an the topic of efficencey of spark in the chamber and atomization. I just want know what happens to the velocity, psi and cfm of air when it passes though different size tubing... with the turbo spool being a constant. Can I speed up velocity of air with in the charge pipe with change of wall structure and without change in turbo Rpm?... if so can does this change PSI or torque of the air?

 

 

go to barnes and noble and by the book <U>Combustion</U> it will teach you everything you want to know.

 

There is the law of areodynamic flowing control. It states that when a molecule of air flows over a certain surface the inverse relationship to it is 1 over pie. It is this because its like taking a carrot and sticking it in a wind tunnel and then making it. But ya the law of areodynamic flowing control was developed by adam pultrey. It also said something about how the shape is affected by the source of the material being used in the progression of air flow. Someone help me out? The differential function law is along the same lines. It says that in order for air to flow freely over a surface it has to have some.

 

hey yo..go to http://www.team-integra.net and go into articles....there u will find an article explain psi and cfm and stuff...i cant give u the link now cuz the site is down or something...its goin really really slow..but yeah just chck it out and look around in the article section...they have lots of great articles..hope that help u out... peace :D

 

i think howstuffswork.com also have something like that

 

I'm no physics major, in fact I hate the class, hahaha. But I do know that if you change the size of the piping, it will affect the velocity of the air. If the piping gets smaller, the velocity will increase. That is why there are always large wind gusts in gorges, because the air is being compressed= more pressure= increase in velocity. Sorry if you already know all of this, like I said, I dont know too much about physics, i'm an architecture major

Air has torque??? Woah - I missed that in school!

WOW!

When the pipe gets smaller, the velocity gets higher. But the amount of air (mass flow rate) stays the same. At the higher velocity it has lower static pressure, but the total pressure is the same. You gotta consider static pressure, stagnation pressure, and total pressure. They're different when there's any velocity.

If your pipe size changes 'smoothly' then this drop in static pressure is recoverable. Sudden changes in pipe size & direction give you non-recoverable pressure loss. Friction is everywhere, & it's ALWAYS non-recoverable.

Want more?? Go to a campus bookstore somewhere that teaches engineering, get yourself a first-level undergraduate fluid mechanics textbook. Look up 'Bernoulli'. Probably better than a physics text.
