Question

what is velocity gradient ?​

Answer 1

Velocity Gradient:-

❥In continuum mechanics, the strain-rate tensor or rate-of-strain tensor is a physical quantity that describes the rate of change of the deformation of a material in the neighborhood of a certain point, at a certain moment of time.

Answer 2

Answer:

For example: rate of change of displacement is called velocity. ... So in your case velocity gradient means how is the magnitude of velocity varies with distance. For example: when fluid is flowing through a pipe velocity of each layer is defined from the axis of cylindrical pipe.
