??? I have to represent an internal combustion engine exhaust flow rate in Feet Per Second. The stack is 8 inches in diameter. Manufacturer's data give me an exhaust flow rate of 2425 Cubic Feet Per Minute. How do I get to FPS?? (Or can I??)

You just need to divide the CFM by the cross secional area of the pipe. Though they both need to be in the same unit, such as feet.
8 inchs = 0.666667 feet
A 0.666667 diameter circle has an area of: Pi * (0.666667 / 2)[sup]2[/sup] = 0.348889 square feet
