Water will be circulated through a full size bypass in the loop, several floors away from the plant. The chiller has remained unused for about 2 years, but care was taken before it was abandoned. Chiller was drained down, refrigerant removed, and charged with nitrogen. The tubes will be...
How would you create an artificial load on chilled water piping in order to perform a capacity verification on a chiller? The chiller is connected to an 8" piping loop, but with no air handlers or coils connected tied into it since it's been abandoned for some time. I imagine that there is...

There is no code or standard where it is simply laid out saying a 1hr wall requires FD and a 2hr wall requires FSD. Am I wrong in believing that the rule of thumb is flawed? And...
I've been taught to use a rule of thumb of calling for fire dampers in ductwork penetrating walls with a 1-hr fire rating; and calling for combination fire-smoke dampers in ductwork penetrating walls with a 2-hr fire rating.
The problem is that I have no idea where this rule of thumb came from...
