AD2000 B3 - Nozzle in knuckle region

[u236]

Dear All,

I have two holes on the head, the first is 150 mm and is inside 0,6*Da, but the second is 47 mm and is outside 0,6*Da
Which diameter I have to use to calculate di/Da and Beta?
I think that because only the hole of 47 mm is outside 0,6*Da, I have to use this one.


Waiting for your kind reply,
