You're probably right Paul, but I'd have guessed that the pressure drop
between the various locations depends on the flow rate and the diameter of
the hose.  At low flows, you're certainly right.  As the flow rate
increases, it seems like the resistance to flow per unit length starts to
become an issue.


Matt-

I agree but with a 3/8th ID line that is rather generous
for 10 gallons an hour.
