Pipe Fittings K Factors for 56" Pipe

[Physics_Nerd]

I am looking for a standard table from IPC/UPC/ASHRAE/ANSI/ASME etc for pipe fittings k-factors, for larger pipes like till 56" (carbon steel with cement lining) I have reference for equivalent fitting method but I need K-factors for pipe fittings/valves for pipes as large as 56" or larger even

kindly help anyway you can

56 is a very odd diameter, but it is your design, not mine.
First, get the K factors for every fitting in 48 inch dia with the correct inside diameter AND liner thickness AND liner material for your 56 inch fittings.
Repeat for the 60 (5 foot) and 72 inch (6 foot) diameter fittings.

If the 56 values are not consistent with the trend between all sizes (regardless of what source you are given), use a different source.

The two most used methods for including the pipe size in calculating K values for fittings are the 2K method by Hooper and the 3K method by Darby. There are many resources on the internet (and right here in Eng-Tips) for these methods. I have written an article that describes them and how they compare with the traditional methods. This article also discusses conversion of equivalent lengths to K values and this should help you evaluate how consistent the data you have is with these methods.
