The flow is infinite in the two directions into the page and in the direction of the flow. There is no driving force like a pump or gravity to change the pressure anywhere, so it is constant everywhere.

Very informative & explaining. You're a lifesaver
5:25 we found V= 0 everywhere. How come in 6:40 u is not equal to 0 then?
v is the vertical component of velocity vector V. Here v = 0 but u is not zero.
V is the velocity of the moving plate
Why do we take pressure as constant?
The flow is infinite in the two directions into the page and in the direction of the flow. There is no driving force like a pump or gravity to change the pressure anywhere, so it is constant everywhere.
How we can investigate the effect of non-zero pressure gradient on the velocity profile?
But if the velocity changes in y direction then how is pressure constant?
Thank you Sir

How did you define BCs please?
No-slip condition.
