Which of the following statement is FALSE? Flow is described as uniform if the velocity, pressure and density at a given instant is the same in magnitude and direction at every point in the fluid. In two-dimensional flow it is assumed that the flow parameters may vary in the direction of B flow and in one direction at right angles, so that the streamlines are curves lying in a plane and are identical in all planes parallel to this plane. A steady flow is one in which the velocity, pressure and cross-section of the stream may vary from point to point but do not change with time. (D) At steady uniform flow, conditions do not change with position or time. The velocity and cross-sectional area of the stream of fluid are the same at each cross-section Flow is described as one-dimensional if the factors, or parameters, such as velocity, pressure and elevation, describing the flow at a given instant, vary only along the direction of flow and not across the cross-section at any point.

Which of the following statement is FALSE? (A) Flow is described as uniform if the velocity, pressure and density at a given instant is the same in magnitude and direction at every point in the fluid. In two-dimensional flow it is assumed that the flow parameters may vary in the direction of B flow and in one direction at right angles, so that the streamlines are curves lying in a plane and are identical in all planes parallel to this plane. A steady flow is one in which the velocity, pressure and cross-section of the stream may vary from point to point but do not change with time. D At steady uniform flow, conditions do not change with position or time. The velocity and cross-sectional area of the stream of fluid are the same at each cross-section re Flow is described as one-dimensional if the factors, or parameters, such as velocity, pr E and elevation, describing the flow at a given instant, vary only along the direction of flow and not across the cross-section at any point.
