Question

Circle all that apply: The velocity field, V vector = 2xti + 3ytj, is One dimensional flow two dimensional flow three dimensional flow steady flow unsteady uniform A streakline consists of all particles in a flow that have previously passed through a common point. is the line traced out by a given particle as it flows from one point to another. is a line that is everywhere tangent to the velocity field. A streamline consists of all particles in a flow that have previously passed through a common point. is the line traced out by a given particle as it flows from one point to another. is a line that is everywhere tangent to the velocity field. Given the velocity field, V vector = 2xy^2ti + 4yx^2j, fill in the following blanks: Find a streamline that passes through the point (2, 3) at time t = 0.5 s if the velocity field is given by: V vector = 2xy^2ti + 4yx^2j.

Explanation / Answer

here,

1)

V = 2 x t i + 3 y t j

as there is velocity flow in both x and y direction only

so the flow is in two dimensions

and

the velocity function is dependent on time

then the flow is known to be unsteady

so, the correct options are b) two dimensional flow and e) unsteady
