Homework Help: Simple question: Maximum Velocity of Airflow

  1. Nov 15, 2004 #1
    Given: you've got a 2.5 inch diameter pipe ... how much air can flow thru the pipe at stoic pressure (14.7)?

    slightly harder (I think) ... this pipe is 6 ft long, how long would it take to compress the air inside the pipe to 20.7psi, and what would airflow be?

    This sounds like a homework problem and depends an awful lot on how complicated you want to get with your calcluations. For a start though, use Bernouli's equation, use 14.7psi as you dynamic pressure and calculate the velocity.

    The second question doesn't give enough information.
