18,000 cubic feet/minute divided by 6 square feet equals an average velocity of 3,000 feet/minute, or 34.1 miles per hour.

Four 5.9's on a sled-pullin' rail-frame, all breathin' thru the same air filter?

Is there a non-standard cubic feet measurement that I should know about?

As opposed to NON-ACTUAL cubic feet? I guess I'm slow, never mind. Is there like a correction factor to convert cubic feet to actual cubic feet? I'm an electrical nerd, I don't get mechanical things!
