Question

Explain velocity gradient in steady flow​

Answer 1

Answer:

The difference in velocity between adjacent layers of the fluid is known as a velocity gradient and is given by v/x, where v is the velocity difference and x is the distance between the layers. ...

Answer 2

Velocity gradient in steady flow is defined as the rate at which velocity changes as a function of distance from the stationary layer.

• When the magnitude of velocity varies distance it is referred to as Velocity gradient. Here distance refers to the distance between the adjacent layers of fluid.
• The velocity gradient is given by the expression dv/dx which means it’s observed in the fluid flowing in a pipe in which change in velocity ‘dv’ between two layers of fluid separated by a certain distance ‘dx’ is measured.
