the pressure drops of the parts can only be found at certain flows, and when you cross them with the D5 pq curve, the flow is not the same.

so i am very confused. how do you find the flowrate given a pump and the parts?
Add up the pressure drop vs. flow curves...sorta hard to do but you could probably get an approximate equation for each and then add. Then as for tubing...there's theoretical pressure drops for tubes, so I'd take however many feet you're using, and add a little more on top of that because of bends. Hope that makes sense...
