Hi.
Question:
Where can I get the values for "Regular 45, 90 and 180 Elbow"?
Details:
We are in the process of checking the piping calculations.
The test systems consists of a mechanical equipment, 2 pipes and an elbow.
The results for the pressure loss is different.
The pressure drop for pipes is matching so the problem lies with the elbow (M_Elbow - Generic: Standard)
I checked values in 2009 ASHRAE Handbook. I would like to know which exact table the above mentioned family is using.
Thanks 🙂
Hi A3D.Razvan,
Checking with development, the source for the Pipe K Factor tables does not come from ASHRAE, rather it comes from Engineering Data Book

Hi, John.
Thanks a lot for your quick answer.
It would be great to have those values in a readily available format from Autodesk (e.g. an Excel / csv file).
This would enable specialists from other countries to back-track and compare the various calculations.
Best regards,
Razvan
