I didn't even consider the flow necessary for 3000 cups per hour...

Why, oh why do people get hung up on formulas?  As you said, "not sure if
this is the correct formula to use, since it may be related to
moving fluids."
The very first thing to do with any problem is to analyze it and identify
its separate components. Then it's simple. Did I miss something?
A 300ft WC is about right for 9bars of pressure. You find the right formula
and solve it. Meanwhile, I'll start building the 300ft tower and get the
tank and water lines started, clear it with the FAA...
I have an espresso machine design in mind with a couple of functional
heating and brewing alterations. Even if expresso estraction were a patented
process, it wouldn't matter. If I can make it work, mine will be "Open
Source," for anybody to copy, modify or reverse engineer- whatever works.
If you worship formulas, describe the transmission of motion and torque by
helical spur gears. Dad wrote the book 64yrs ago.

i hate formulas, id move on if i could, but sooner or later someone will
want a shot of coffee, and so, the fluid moves.. :p
now, though, we have force in addition to pressure, and area has a direct
impact on force of a moving fluid. plus theres rate of flow, which may be
negligable since its only coming out in short (and hopefully controllable)
bursts.
