Problem

A tank open to the atmosphere has a small orifice

0.50\,\text{m}

below the free surface of water. Neglecting viscosity and taking

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

, calculate the speed with which water emerges from the orifice. (a)

4.4\,\text{m s}^{-1}

(b)

9.8\,\text{m s}^{-1}

(c)

3.1\,\text{m s}^{-1}

(d)

2.2\,\text{m s}^{-1}
