Can air pressure stop in a pipe?

  1. Jan 31, 2015 #1
    Hi guys

    Im trying to understand something..
    If air is coming through a pipe, at a variable fan speed. (0.0053 m3/s) and the pipe is 10 meters long and coiled.

    Will the air reach the end of the coil?
    Or can air just loose pressure at a certain point?

    Air cannot vanish. If some flow goes in, flow comes out with exactly the same mass per time.
    Your pipe can lower the amount of inflowing air if pressure builds up at the entrance.
