Question:medium

The velocity field on an incompressible flow is given by $\overline{v} = (a_1x + a_2y + a_3z)i + (b_1x + b_2y + b_3z)j + (c_1x + c_2y + c_3z)k$ where $a_1 = 2, c_3 = -4$ then the value of $b_2 = _$

Show Hint

"Incompressible" is a keyword in physics and math that always implies $\text{div } \overline{v} = 0$.

Let $ R $ be the planar region bounded by the lines $ x = 0 $, $ y = 0 $ and the curve $ x^2 + y^2 = 4 $ in the first quadrant. Let $ C $ be the boundary of $ R $, oriented counter clockwise. Then, the value of:
\[ \oint_C x(1 - y) \, dx + (x^2 - y^2) \, dy \] is equal to:
