can you help with this generator problem?

Question

i'm trying to build an hydrolically fillid neutral gas canister generater with aperature that emits gas that spins a centrifugal turbine it's my own idea as far as i know but i could use help with aperture size ? what aperature do i need to create sufficient motive force to create motion in centrigul has resistance of 1 to 3 lbs and gas tank is 10 cubic normal gallons

the pressure is variable and increasable i was wondering a pen tip nozzle with nearly direct contact with a laddered centri-fugal wheel i got the idea answering a centi mechanics your answer tightened my design but i don't plan to make any money from i was trying something different from water wheel but similar

i don't mind other people trying idea just do safely
if pressure /velocity highenough might actually generate electricity

cannister pressurized with contracting hydrolics i.e. sliding piston possible rest period to refill with double fill technique
just a hypothosis

u helped maybe tube can with reaming piston ala musket might work for me any ideas that might help these already exist but what if used to propell centrri- generator

electric generator,,,hydrolically pressurized gas,,, just schematics

Answer 1

I am interested in your project even though I have no idea what you would want such a thing for

I have some experience sizing fluid flow orifice's and nozzle's and the like and I might could offer some suggestion on aperture size if I could tell what any of your units are

10 cubic normal gallons, I assume is just 10 gallons
1 to 3 lbs of resistance, I have no idea if that is a resistant force (in lbs-force) or some other unit

I assume that you are actually looking for a certain velocity of gas out of your apeture, that is a fairly straightforward calculation if you know the pressure in the cannister

If the pressure in the cannister is changing and you want to maintain an exit gas velocity, then you have to have a changing apeture size (control valve)

I can't tell what your actually trying to accomplish, but a variable apeture is often a good thing to have during a design phase

are you trying to generate electricity using pressurized gas as a motive for a turbine?
if so, how are you going to pressurize the gas?
