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. To keep one layer of fluid moving at a greater velocity than the adjacent layer, a force F is necessary, resulting in a shearing stress F/A, where A is the area of the surface in contact with the layer being moved.

How does a streams gradient affect of velocity?
The steeper the gradient, the higher the velocity of flow.
What is the rate of change of velocity with distance called?
Known to be "VELOCITY GRADIENT"
What are the units of velocity gradient?
The velocity gradient (du/dy) where du is the change in velocity and dy is the change in distance between plates, would have units of (1/time) or (1/sec).Hope this helps!
How is acceleration obtained from a velocity line graph?
the gradient of the graph
How does a stream's gradient affect its velocity?
the difference in velocity is mostly due to the great efficiency of the large downstream channel.
How does a streams gradient affect of velocity?
The steeper the gradient, the higher the velocity of flow.
Stream gradient role on stream velocity?
An increase in gradient will generally increase stream velocity.
What is the rate of change of velocity with distance called?
Known to be "VELOCITY GRADIENT"
What does the River flow velocity depends on?
the gradient and how much friction there was. The gradient means how steep the land the river is on so if it is very steep them the velocity will be higher.
What is the definition of velocity gradient?
With respect to material being sheared, velocity gradient is the change dv in relative velocity v between parallel planes with respect to the change dr in perpendicular distance r throughout the depth of the material. Velocity gradient has the same dimensions as rate of shear, which is reciprocal seconds.
What are the units of velocity gradient?
The velocity gradient (du/dy) where du is the change in velocity and dy is the change in distance between plates, would have units of (1/time) or (1/sec).Hope this helps!
How is acceleration obtained from a velocity line graph?
the gradient of the graph
What is the dimensional formula of velocity gradient?
Velocity is L/T, gradient ("per unit distance") is 1/L so L/T x 1/L = 1/T
How does a stream's gradient affect its velocity?
the difference in velocity is mostly due to the great efficiency of the large downstream channel.
How do you calculate deceleration on a velocity time graph?
It is the downward gradient of the graph.
If the pressure gradient force's rate of elevation is steep wind velocity is?

What is the relationship between shear stress and velocity gradient in a Newtonian fluid?
linear
