Problem

A sealed tank holds water to a depth of

1.20\,\text{m}

. The air above the water is maintained at a gauge pressure of

3.0\times10^{4}\,\text{Pa}

. A small opening is drilled through the bottom of the tank so the water exits into the atmosphere. Determine the speed of the water as it leaves the hole. (Water density

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

.) a)

4.9\,\text{m/s}

6.4\,\text{m/s}

9.1\,\text{m/s}

7.8\,\text{m/s}
