Zeta value
Zeta value
(OP)
My European affiliates have asked several times for Zeta values. It is supposed to be some sort of flow restriction index, but unlike the inverse of a Cv value, Zeta can be the same value for different sizes of valves.
Can someone please enlighten me as to the definition of Zeta, and how I might tabulate it?
TIA
Jim
