Hydraulic Losses Through a Pipe

[cbennett3]

TL;DR Summary

To help better understand the minor losses through a tap on ductile iron pipe.

I am trying to estimate the pressure loss from a tap to a piece of equipment we are feeding water to. I have the pressure on the 12" ductile line. I have the friction losses in the different pipe sizes (1",1.5", and 2") for the service line. I also have the losses through the 1" meter. The only thing I lack is the actual losses through that 90 deg. turn at the tap on the 12" main. We already have a 1" tap and want to use it then up size to a 2" service line and feed the piece of equipment. But if there is too much loss through that 1" tap we may have to make a new 2" tap. How can I estimate the losses through that 1" vs a 2" tap.
