Pelton Wheel for Power Generation

AI Thread Summary
A Pelton wheel can effectively generate power at 45 psi, which falls within the optimal operating range of 15-1,800 meters head. To determine wattage and amperage for 12, 24, or 48 volts, both water pressure and flow rate must be considered, as they directly impact power output. Sufficient water flow is essential, and using two half-inch nozzles may help optimize performance. Care should be taken not to draw too much power, as this could reduce water pressure for downstream users, potentially leading to complaints. Overall, while the concept of harnessing water power is appealing, it requires careful planning and consideration of local water supply dynamics.

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

:welcome:

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. :smile:
 
Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
Thread 'Beauty of old electrical and measuring things, etc.'
Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
