Has anyone had any experience using Cameron Hydraulic Data for their head loss calculations? I was recently checking some head loss calculations when I discovered that the head loss I had calculated was almost double of what was previously done. Doing some backchecking we found some discrepancies between what Cameron uses for head loss and what other sources use. For example, for a 16" CHW Sch. 40 steel pipe at 6,000 GPM, Cameron has a head loss of 9.31'/100'. ASHRAE has the head loss at around 2'/100'. I checked other sources (Bell & Gossett/Carrier/etc) and they all agree with ASHRAE's estimate.
Can anyone explain such a large discrepancy, or has any experience with large differences between Cameron and other sources?
