hello i copied a question on nov 2009

(1.1414 xoffset) -2 (.414x (clr) centre line radius this is the formula

example degree of elbow: 60=.577

45=.414

30=2.00???????????is.268

example in your situation

45 degree elbow 48x20

(1.414x36 offset)-2(.414x72)

=21.288 thats the length of the duct in between your on your two 45 degree elbow...

my question is: let's say the 48*20 offset of 36" got to fit in 75" space

it might fit for all degree 30,45,60 with any kind of radius

but if i pick 45º and clr and if fit within 75" : i want to know the diaganal lenght between offset plus know the straight at one end to reach 75"

plus even more challenge: have a formula to find the exact degree elbow & clr (ex. 55º & 112"clr)with no straight in between if possible in that case

i've been trying to find that formula for many years

hope you understand my question

thanks
