Velocity of the pressure change

  1. May 31, 2015 #1
    Hej guys,

    Do you know how to calculate the pressure re balancing time in an underwater container where the liquid were de -pressured by taking very small amount of liquid away (just to have the normal enclosed liquid's gravitational pressure there, without the external water column's pressure). Opening a door would be the method for the re-pressurizing. So calculate instantaneous the water displacement and only the time requires to the pressure wave to balance the pressure needed...

    Thank you very much!

    Pressure changes usually propagate with the speed of sound in the medium. Reaching a good equilibrium can need longer in the same way as sound waves can bounce around in a room multiple times.
