Yes, spacing depends upon what medium you are using. I have seen some
specs floating around there some where. Mediums like water that have a
greater surface tension were like .017 Whereas air would be more like
In response to your question about holes, I was thinking the same sort
of thing, only working the unit in reverse. The pump would have a water
jacket that would be pressurized. The fluid would flow into all the
holes, distributing the pressure across the perimeter of the disk.
However, each time you add a hole, you are adding surface area and
resistance. Said another way, 1 large hole adds less impedance than many
small holes with the same cross sectional void. So, is the advantage
gained by distributing the force more significant than the loss due to
the added drag in the system?
(from memory, someone correct me here...)
Interestingly enough, I just bought a book that is a collection of all
tesla's patents... It's almost 2" thick!

Subject: [TeslaTurbine] Disc spacing and discharge
Has anyone established what the optimum disc spacing should be? Also
any thoughts as to having the working fluid exit out the perimeter of
the housing vs holes in the disc?------Phil
