Hi,

I am new here and very new to refrigeration. I have a simple question for you guys which I am failing to find a definitive answer to.

What measurement should I add onto the total length of pipe for swept bends and 90 degree pulled bends please? I have asked a few refrigeration friends and they don't really equate the bends in as they argue it is the same internal diameter as it was, but surely frictional resistance must have relevance. Need a practical answer to this please

Cheers,

B
