Problem

An open tank contains water. A small orifice of area

2.0\text{ cm}^2

is located

1.6\,\text{m}

below the free surface. (i) Find the speed with which water emerges from the orifice. (ii) Determine the volume flow rate through the orifice. (Use

\rho = 1000\,\text{kg}\,\text{m}^{-3}

g = 9.8\,\text{m}\,\text{s}^{-2}

) a. (i) Speed of efflux b. (ii) Volume flow rate
