Homework Help: Fluid flowing in a sphere and leaving

  1. Sep 16, 2013 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations

    3. The attempt at a solution
    Just checking if this is correct, and if the equation in part c implies that the flow rate out changes with time, or is just based off the initial height..I think it changes and therefore requires this integration. Also, I looked up the equation for the volume of a liquid that is not filled up, not sure if it is correct or not

    The flow always depends on the current height, of course - benzene has no "memory" of some initial height. The physical reason for the height-dependence is the pressure at the bottom, which drops with a reduced height.
