Problem

A sealed tank holds water to a depth of 1.20 m1.20\,\text{m}. The air above the water is maintained at a gauge pressure of 3.0×104 Pa3.0\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 =1.0×103 kg/m3=1.0\times10^{3}\,\text{kg/m}^{3}.) (a) 4.9 m/s4.9\,\text{m/s} (b) 6.4 m/s6.4\,\text{m/s} (c) 9.1 m/s9.1\,\text{m/s} (d) 7.8 m/s7.8\,\text{m/s}
