But, Here's an analogy. Imagine that you've got a 100' length of garden hose connected to your outdoor spigot (sp?). The valve is wide open. The water coming out of that hose isn't going to have a whole lot of pressure, due to the resistance of the hose. It follows that the velocity of the water coming out of the hose isn't going to be very great, either. If the hose were removed from the spigot, or a shorter hose was used, there would be a much higher pressure & velocity, therefore a higher flow rate.
Now I know that there cannot be more water going into that hose than what is coming out of it. (at least after the water's been running for a bit, and the pressure differences w/in the hose have been established) Speaking of which...
Back to our 100' hose. If it sprung a leak close to the spigot, the leak would spray out w/ great force. If the leak happened at the end of the hose, you'd be lucky to get a trickle. Hence, a pressure difference.
You know... I really don't know how to quantify what I am thinking, but it makes sense to me.
Here's a thought. The volume of water going into a circuit/pump has to be the same as the volume coming out. Water moves slower as it passes through large spaces and faster when it travels through tight spaces. Perhaps this exlains why some pumps' intakes are bigger than their exhausts. What if you had a system the had a smallish hose from the pump to the WB for max velocity, and medium size hose from the WB to the rads, and a large hose from the rads back to the pump. The water would continuously move from an area of higher resistance/velicity to an area of lower resistance/velocity (ideal for WC setups). I suspect that this setup would yield higher flow rates than a system that was setup in reverse (slow, low pressure water moving into areas of high resistance). The second system would be less efficient than the first.
Does this help? I'd like the pro's input too.

okok..i THINK I get what you're saying. thanks
ok, is this the new consensus then? that best order is pump->block->radiator->pump is best?
