A large pipe with a cross sectional area A1=1.2 m2 has water flowing through it. The pressure in the pipe there is maintained at atmospheric pressure. The pipe then descends 3.7 m and narrows to a new cross sectional area A2. Water exits the pipe there into an environment at atmospheric pressure. What must the cross sectional area A2 of the pipe be in m2 if the water is exiting the pipe with a speed of 9.8 m/s?

    PRACTICE IT Use the worked example above to help you solve this problem. A large pipe with a cross-sectional area of 1.24 m2 descends 4.80 m and narrows to 0.500 m2, where it terminates in a valve at point (see figure). If the pressure at point is atmospheric pressure, and the valve is opened wide and water allowed to flow freely, find the speed of the water leaving the pipe. 4.43 Your response differs from the correct answer by more...
