A closed and elevated vertical cylindrical tankwith diameter 2.00mcontains water to a depth of0.900m. A worker accidently pokes a circular hole withdiameter 0.0190min the bottom of the tank. As the water drainsfrom the tank, compressed air above the water in the tank maintainsa gauge pressure of5.00�103Paat the surface of the water. Ignore any effects ofviscosity.
A. Just after the holeis made, what is the speed of the water as it emerges from thehole? in m/s
B. What is the ratioof this speed to the efflux speed if the top of the tank is open tothe air?
C. How much time doesit take for all the water to drain from the tank? in min
D. What is the ratioof this time to the time it takes for the tank to drain if the topof the tank is open to the air?
Please help I have no idea how to solveit
