Rex - I enjoyed reading part II of your article. I can't stress how important frictional losses are when picking out a pump for a return. So many people over look this critical step during the process and wonder why their return rate is so poor!
I would have spent more time on the subject myself. :d
I believe some comparisons would have helped you to bring your point across. Some people "understand" the point better when the data spelled out for them.
Also, frictional losses have their limits as well. There's a point of "diminished returns". Friction will always occur, no matter how smooth or how large the pipe diameter is.
I know most people use the "one size above your outlet" rule; this however really doesn't work in most cases. The velocity of the water being moved needs to be considered as well. Two sizes above the outlet usually works the best, again, not in all cases.
