Application of Bernoulli's Equation Physics question on FLUIDS unit

  1. Oct 19, 2005 #1
    A large root beer keg of height H and cross sectional area A1 is filled with root beer. The top is open to atmospheric pressure. At the bottom is a spigot opening of area A2, which is much smaller than A1.
    Find the total time needed to drain the keg if H=2m, A1=.8m^2 and A2=10^-4 * A1.

    u can use toricellis' law of fluids

    v = sqrt(2gh)

    you can then take the mass flow rate to find the time right
