    A liquid is allowed into a tube of truncated cone shape. Identify the correct statement from the following.

    A)  The speed is high at the wider end and low at the narrow end

    B)  The speed is low at the wider end and high at the narrow end

    C)  The speed is same at both ends in a stream line flow

    D)  The liquid flows with uniform velocity in the tube

    Correct Answer: B

    Solution :

    For an incompressible liquid equation of continuity Av = constant or \[A\propto \frac{1}{v}\] Therefore, at the wider end speed will be low and at the narrow end speed will be high.
