(Design) formulae for reducers - contraction angles etc.
(OP)
Does anyone knows of any publication, design info sheet or such (I couldn't find it in any ASME code/standard anywhere),
where I can find the (physical) design, with respect to dimensions and angles, for a (concentric) reducer?
I'm having a hard time defining the K-factor as I don't know several parameters like the exact angle of contraction, etc.
I do know the overall dimensions, and inside radii, but there's more info required for determining the K-factor.
Also, are there any limits as to how fast/sharp the contraction/reduction may occur, or how smoothened it should start?
Thanks in advance.

For some indication of the variablilty in the real world have a look at htt
Then you can laugh when people argue over whether the K-factor of a fitting is actually 0.26 or 0.28.

Thanks katmar, for the useful link. As you implied, I already thought it's almost impossible to define 'the' K-factor of a fitting. Knowing the range it may operate in at least gives a better engineering approach.
