Question

Dimension of velocity gradient and its derivation

Answer 1

Answer:

Velocity gradient is the change in velocity with respect to distance. The mean velocity gradient is the average value over some of the gradient over some distance.

The dimensional formula of velocity is L1M0T−1 and that of distance is L1M0T0.

⇒ The dimensional formula of mean velocity gradient is

L1M0T−1 /L1M0T0.

=L0M0T−1.
