Problem

A large cylindrical tank of cross-sectional area

A = 10\,\text{m}^{2}

has a small orifice of area

a = 0.01\,\text{m}^{2}

at the bottom. Water is initially at a height of

4\,\text{m}

. Calculate the time required for the water level to drop from

4\,\text{m}

1\,\text{m}

. Take

g = 10\,\text{m/s}^{2}
