Question
Consider the velocity field v = y²i — x²j – z²k.
-
Evaluate the divergence and curl of this field at the
point (1, 2, 1) and use your answers to select the
two options that describe the behaviour of v in the
immediate vicinity of (1, 2, 1).
Select one or more:
A flow corresponding to an anticlockwise
rotation about the z-axis when viewed from the
positive z-axis.
A flow corresponding to no rotation about the z-
axis.
A net inward flow.
No net inflow or outflow.
A flow corresponding to a clockwise rotation
about the z-axis when viewed from the positive
z-axis.
OA net outward flow.
