I failed to respond last year when this was first posted, but I will
now. I do not see how 90 degree bends in a fluid transfer systems would
kill life. You have to look at the velocity profile of water moving in
a pipe to realize that irregardless of the direction or route, you are
going to have laminar flow. The greatest velocity would of course be in
the center of the pipe, while do to the co-efficient of friction between
the fluid and the pipe, the smallest velocity would be in the "boundary
layer" next to the pipe wall. This boundary layer, to my way of
thinking, would be the most destructive to the living organisms in the
CT, due to friction. This would hold true in a 90, 45, or even a
straight pipe. The fluid just doesn't shoot through the pipe and go
splat on the wall of a corrosponding elbow.
