Part C How much time does it take for all the water to drain from the tank? A closed and elevated vertical cylindrical tank with diameter 2.20 m contains water to a depth of 0.900 m. A worker accidently pokes a circular hole with diameter 0.0160 m in the bottom of the tank. As the water drains from the tank, compressed air above the water in the tank maintains a gauge pressure of 5.00 x 103 Pa at the surface of the water. Ignore any effects of viscosity.

CE Part A Just after the hole is made, what is the speed of the water as it emerges from the hole? A closed and elevated vertical cylindrical tank with diameter 2.20 m contains water to a depth of 0.900 m. A worker accidently pokes a circular hole with diameter 0.0160 m in the bottom of the tank. As the water drains from the tank, compressed air above the water in the tank maintains gauge pressure of 5.00 x 10 Pa at the surface of the water. Ignore any effects of viscosity. ΙΤΑΙ ΑΣΦ ?
