Subject: SS Pipe penetration into anechoic chamber friction loss

Happy new year sprinkler guru's,
I have attached a picture of a fabricated 1½" stainless steel pipe penetration 
that we are supposed to connect our sprinkler drops to (on the roof of) an 
Anechoic Chamber. The client also wants flexible drops. Without addressing the 
"listing" of this component, I am looking for a "C" factor for this. I have 
contacted the manufacturer (German company) but they do not have any friction 
loss data. Have any of you dealt with this before?
Thanks in advance for your input.
