I really want to learn, and come up with the truth. I have done expiriments on my case and certain Hose's.
Now, there is NO dispute that 1/2 ID hose is less restrictive then any smaller ID hose.
The problem I have is that I beleive, and I may be wrong, that the smallest hose size or restriction will ultimately be the weekest link in the chain. This makes sense only because unlike a gas, water doesnt compress.
Therefor in theory, based on the above theory; you could run the following expiriment.
Requirements:
Pump Size, Voltage, ube length and Tube loop height must remain constant. The Pump and Hose must be completely full, and pump running before any measurements are takin. The Pump must be extremely powerfull, with high flow and high preasure.
Experiment Procedure
We use 3 different hoses. Hose "A" is a 1/2 ID, Hose "B" is a 1/4 ID, and Hose "C" is a 1/2 ID with a reduced section measuring 1/4 ID.
Each expirement would require a Fill Bottle and a Drain Bottle. Each Hose (A-C) would undergo the same expiriment. The pump would be turned on, and would fill the fill bottle until all bubbles are removed. It would be marked and a Time would be taken. After 60 seconds, the waterlevel marked again.
Measure the difference and you get the flow rate of each hose over one minute.
Expected Result: Hose A would have the highest flow rate. Hose B would have the secondhighest, but by very small difference bettween Hose C
Lastly The expirement should be repeated with a lowflow high pressure pump.
In this case I would expect all 3 Tubes to remain constain in flow rate.
What do you guys think, and please provide resources, or if you can, complete the expiriment. I got to run, I will provide details of my experiments results, with you later today.
Edit: Definitions for the Noobies
OD = Outside Diameter, size of the hose on the outside.
ID = Inside Diameter, size of the hose on the inside.
Compression Fittings = Hose Clamps that have small barbs, and screws that tighten around the hose to compress the tube from falling off. Always steal or metal
Barbs = Plastic or metal parts that slide into the tube, and that have a ridge that prevents the hose from sliding off. Don’t be fooled, always use clamps to secure your barbs. Non Secured Barbs will probably leak after some time.
Clamps = "C" metal clamps found at home depot, which are made out of steal and that are tighten with a screw driver. Over tightening C clamps can break plastic barbs, or can damage hose over time. Plastic Quick clamps work well and are also a valid product. Prefered for some hose sizes, they are easily applied, are non-conductive and are safe and can help prevent from over tightening that occurs with C clamps.

And, there are good arguments for both high flow and low flow systems.
