Problem

A sealed cylindrical tank contains water with its top surface

2.0\,\text{m}

above a small opening at the bottom. The air space above the water is pressurized to

1.30\times10^{5}\,\text{Pa}

(absolute), while the outside air is at

1.01\times10^{5}\,\text{Pa}

. The density of water is

\rho = 1.0\times10^{3}\,\text{kg}\,\text{m}^{-3}

. Assuming the water level remains steady, determine the speed of the water as it leaves the opening. Use

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