Pelton Wheel for Power Generation

[Alfredo]

I am a simple Newbie, wanting to make power, using Pelton wheel say 45 psi water pressure , 3/8 to 1/2 nozzle...is there a way to determine the results or is there a better psi/nozzle combo? Generator can be 12/24/48 volts

This article https://en.wikipedia.org/wiki/Pelton_wheel#Design_rules shows you how to calculate the performance.

The same article says:

Pelton wheels operate best with heads from 15–1,800 metres (50–5,910 ft), although there is no theoretical limit.

45 psi is within that range.

Keep us posted on your progress.

SO if anyone knows is there a way to determine the wattage and amperage produce-able, for 12...24...48 volts, having 45 psi. I am a novice at formulas.

You will need to have enough flow available at that pressure and orifice size to feed it - what is your source of water?

I have a well that feeds a small neighborhood as it passes my property it has 45 psi per gauge, i was going to implant an encapsulated pelton unit(size to be determined) ,as everyone fills their tanks, constantly.One inch and a quarter line. So two orifices at half inch?

And what maximum rate of flow do you get? As has been pointed out already, Power out will depend on water pressure and flow rate. If you try to take too much power from this water feed, people downstream of you will suffer a reduction in water pressure / flow. This may or may not be relevant. but if they become aware of this and if they know you have 'done something' to their supply, they may complain. Their tanks may take longer to fill if the exit pressure from your generator is significantly lower than at present.
Your power source cannot be totally 'free'. But I can see how tempting the idea is.
