    1. The problem statement, all variables and given/known data
    A large tank is filled with water and open to the atmosphere has a small hole in its side at a point 15 m below the water level. If the rate of flow from the hole is 4.17x10-5 m 3/s .
    What is the diameter off the hole (in mm)



    2. Relevant equations
    R=A*V, where R is the rate flow

    Re: Fluids

    In side the tank at the depth h the total pressure = Pa + ρgh. Velocity of the the liquid is zero.
    Out side the hole the pressure = Pa.
    Using Bernoulli theorem find the velocity of liquid flowing out of the hole, From that find the area of the hole.
