Hi MArtin,
I'm not sure I follow your question. It seems that the rotating wand
would be like a dishwasher spray wand ? it would have many different
holes and they would be angled so the more pressure, the faster it
would spin ?
When you mentioned spinning, the first thing that came to my mind
would be to have a shaft that came out of the enclosure
and that would have a motor on it.
But that would mean a circular spray pattern if the want rotates in a
circle.
dunno what your project looks like.
But, I would be careful about having ANYTHING under pressure that was
NOT in a secondary containment vessle of some sort. If a fitting or
tube were to leak, there should be some means of containing the spray
as well as the fluid.
I would not like any Xenomorph blood on my carpet.
