Water enters a tank through a 10-cm diameter pipe at a velocity of 3 m/s, as shown in Figure P3.5. At the bottom of the tank, water exits at 6 m/s through a 5.25-cm diameter pipe. The depth of the water in the tank is 1.5 m. The tank has a diameter of 1.25 m and a height of 2.5 m. Determine how long it will take for the tank to either overflow or drain.
