Calculation of Flow rate

  1. Sep 25, 2007 #1
    suppose there is an spherical balloon say 100 cu.m . The pressure difference between the air in it and surrounding air is 200N/m2 . If a hole of 1 sq.m is made what will be the flow rate from it. Of course the flow rate will decrease as the time progresses but how to determine it over a period of time??

    Is this a homework problem? What equations apply?

    1 m2 is a BIG hole!

    200 Pa is a very small differential pressure. 1 atm = 101325 Pa = 101.325 kPa = 0.101325 MPa or thereabouts.
