Calculate the speed with which water flows from a hole in the dam of a large irrigation canal. The hole is 0.80 m below the surface of the water. If the hole has a radius of 2.0 cm, what is the flow rate of the water from the hole?

  • physics -

    Bernoulli's equation:

    mgh=1/2 m v^2

    v=1.6g

    flow rate: I assume you mean mass flow rate, not volume rate.

    flow rate=density*velocity*areahole
