A closed and elevated vertical cylindrical tank with diameter2.00 m contains water to a depth of 0.900 m . A worker accidentlypokes a circular hole with diameter 0.0170 m in the bottom of thetank. As the water drains from the tank, compressed air above thewater in the tank maintains a gauge pressure of 5.00×103Pa at thesurface of the water. Ignore any effects of viscosity. Just afterthe hole is made, what is the speed of the water as it emerges fromthe hole? What is the ratio of this speed to the efflux speed ifthe top of the tank is open to the air?How much time does it takefor all the water to drain from the tank? What is the ratio of thistime to the time it takes for the tank to drain if the top of thetank is open to the air?
