since pressure if force/area, and the friction is considered as the force, then if a larger force (friction) is applied to the fluid, would the pressure increase?

also could you please help explain how if the velocity gradient (du/dx) is less than 0, the pressure gradient (dp/dx) will be greater than 0 and vice versa.
