Additional info on NCAR supercomputer facility

The first post was so long I didn't want to go into additional detail, but since you'all asked, here goes:

The 2 foot pipes do carry chilled water solution for cooling the computer cabinets.
In the lower floor beneath the cabinets, those large 2 foot pipes have valves where a 2" (appx) dia hose goes through the floor to the liquid cooling system in each cabinet.
An interesting thing was that the big pipes had only 45 degree bends, too much turbulence or restriction with a 90 degree bend.

Wish I had some pictures to attach, but alas, we were too intent on listening to the guide.

Anyway, it was a great tour and was free.
