I am researching the best shape for a hose clamp to provide a consistent and predictable friction loss in the 1 to 2 psi range. The hose diameter will be either 3 or 4 inches and the water flow will typically be in the range of 10 to 50 gpm. The idea is that the hose clamp can be finely adjusted to a set-point to provide the desired friction loss.
I've considered a "venturi" shape versus a sudden contraction/sudden expansion shape to provide flow characteristics that are predictable but most references that I have look at it from the standpoint of accounting for "minor losses" rather than defining a precise relationship.
My fluid mechanics skills are quite dusty at present and so I would like to see if anyone has any suggestions.
Thanks much.
