I'm not sure, I think I have to move on but if I understand it later I'll let you know

So the negligible mass is important because the force of static friction = uFn, and Fn = mass of boundary layer * g. So because there is small amount of mass, there is a small normal force and a small amount of static friction keeping it from slipping, Is that right?

Thank you. Okay so maybe I'm not understanding friction correctly. The friction force that is allowing the fluid underneath the boundary layer to slide with the boundary layer, is that static friction? I'm sorry if that's dumb I am teaching myself physics.

https://openstax.org/books/university-physics-volume-1/pages/14-7-viscosity-and-turbulence I am trying to understand the derivation from Figure 14.36 which starts with " The fluid to be measured is placed between two parallel plates. The bottom plate is held fixed, while the top plate is moved...

It should be acting to the right, because the pressure is coming from the left side of the fluid and because the velocity is to the right!

I figure that either the Force F2 is applied in the opposite direction because of some kind of resistance, but I'm not sure. Thanks!
