    In a two-dimensional flow, where u is the x-component and v is the y-component of velocity, the equation of streamline is given by:

    A) \[udx-vdy=0\]   

    B) \[vdx-udy=0\]

    C) \[uv\,dx-dy=0\]

    D) \[udx+vdy=0\]

    Correct Answer: B

    Solution :

    Equation of a stream line is: \[\frac{dx}{u}\,\,=\,\,\frac{dy}{v}\] or \[udx-udy=0\]
