Question

The velocity in m/s at a point in a two-dimensional flow is a given as $\overrightarrow{V}$$=2\hat{i}+3\hat{j}$. The equation of the stream line passing through the point is

• A. $3dx-2dy=0$
• B. $2x+3y=0$
• C. $3dx+2dy=0$
• D. $xy=6$

Answer 1

The correct option is A $3dx-2dy=0$

The equation of stream line in two dimensions is given as
$vdx-udy=0$
$\Rightarrow$ $3dx-2dy=0$
