  1. Sep 14, 2008 #1
    A gymnasium is 13.0 m high.

    By what percent is the air pressure at the floor greater than the air pressure at the ceiling?

    so far i have

    P(bottom)=(1.013 x 10^5) + (1.28)(9.8)(13)
    P(bottom)=101463.072
    P(top)=101300.000

    P(bottom)/P(top)=0.161%
    is that correct?

    Hi jason_r,

    That looks right to me (as long as your air density is correct).
