3. A 1.5 m high, 1-m-diameter cylindrical water tank whose top is open to the atmosphere is initially filled water. Now the discharge plug near the bottom of the tank is pulled out, and a water jet whose diameter is 0.015 m streams out. The average velocity of the jet is approximated as v2 gh, where h is height of the water measured from the center of the hole. Estimate how long it takes to empty the tank. (20 points) Air Water 3.
