Hi All -

Is anyone aware of a prohibition against using 45 degree angle ductwork
runs (as opposed to vertical runs) for a perchloric acid fume hood?
This pertains to water washdown systems.  This question was posed to me
and I thought I'd seek your collective wisdom.

I'd appreciate it if you could point me to any references you may be
aware of regarding this subject.
