Head loss in reducers/expanders

Hi all,

I am trying to calculate the head loss in standard reducers (8" to 6") and expanders. However, all the formulas I find use the angle of the fittings..Is there a simpler formula for a 'standard' fitting?

Thanks

Try this one:

(or, in chemwork.org, go to Technical Board, Hydraulics, Contraction, Expansion, Pressure Drop).

Many thanks :)

Thanks Dear,
