Two 45s versus Long Radius 90 - PVC
I know there was some information comparing the SP loss of these two probably by BobL. I have spent a lot of time looking but have failed to find it. It is commonly thought the two 45s are better, I wonder about the effects of the connections inside and turbulence they create.
I would appreciate any help in finding the information.

This is the post where my test results are shown
Air flow calibration measurements
The performance differences will be greater for greater flows so if you are using a small DC or have constricted machinery connections any differences might not be noticeable.
