    Q: A meter long hose of 14cm diameter is connected to a second hose which is 4 meters long and 7cm in diameter. At the open end of the second hose water flows out at a rate of 8 cm^3/sec. What is the ratio of the speed of the water flowing in the second hose to the speed of the water flowing in the first hose?

    1) (v2/v1) = 4
    2) (v2/v1) = 1/3
    3) (v2/v1) = 1
    4) (v2/v1) = 1/2
    5) (v2/v1) = 1/4
    6) cannot be determined from the information given.
    7) (v2/v1) = 8
    8) (v2/v1) = 1/8
    9) (v2/v1) = 3
    10) (v2/v1) = 2

    Answer:

    This is the problem about the flow of a non-viscous incompressible (ideal) fluid through a pipe of ...

    Solution Summary
