Pressure does NOT decrease as the fluid velocity increases.

You are confusing pressure measured parallel to the direction of motion
with pressure measured transverse to the direction of motion. Like I
was before I asked the question.

Actually, I'm not. Read my last post. It thoroughly explains why force
increases both parallel and perpendicular to the direction of motion as
velocity increases. To summarise, in the case of fluid flowing through
a tube, it is because particles continue to collide with the inner
walls of the tubing regardless of velocity...the greater the velocity
the greater the force of collision and therefore the greater the
outward pressure. Although I question whether force increases perfectly
perpendicular to the direction of motion, there is definitely an
increase of force between the two axis as velocity increases.
