Water flow from a tank

  1. Jan 25, 2010 #1
    Hello guys,

    I want to know whether the water flow rate from a tank depends on the geometrical shape of the tank (for instance sperical, rectangular, cylindrical) etc or it just depends on the water level in the tank. Thanx.

    Well if the flow is through a (relatively) small opening, the instantaneous flow rate is dependent on the pressure head, size of opening, and shape of opening.
    V=Cd (2gh)^1/2
    So tank geometry doesn't come into play. Time to empty would be affected by tank size & geometry.
