how was water pressure created for those monitors during the 1840's gold rush?

[look 171]

I looked but can't seem to find the answer?

What was the technology like back then? Not electricity, no pumps, so how was pressure created to wash off the whole hill side? Gravity? how the hell do they get that much water up to high just to feed the large water canons or monitors? They get up to as much as 8" in dia. That's huge.

[Crowbob]

Magnets.

The answer is always magnets.

[Evans, Marv]

I would imagine steam powered pumps might have been involved. I know gravity feed is only something like 3 or 4 psi per ten feet.

That will be a btich getting a large engine or machine up into the steep hills around the area with no roads.

[Evans, Marv]

Yep, probably in pieces & parts.

Helicopter, or UFO.

Gravity back then. The Clint Eastwood movie Pale Rider explained it rather well.

Found some of the dialogue here (great movie):

I think it was just hydrostatic

they built a pipe line far upstream and as the line got closer to where the nozzle was at a lower elevation, they used smaller diameter pipe

as the water flows down hill it exchanges potential energy for kinetic energy and when comes out the nozzle its going pretty fast

^this

Gravity and a stepped down smaller pipe,

Look, I've got no idea re the question. But it looks like you have an interest in finding gold. I'm obsessed about "Aussie Gold Hunters". You can find it on youtube, but we get it on TV a number of times a week. I'm on the edge of my seat cheering them on LOL

Blimmin' Australia, the place is full of the stuff.

I think my recolection came from this movie

funny thing with California,

when I used to have a Scout and was in a 4wd club, the trails in California were really soft compared to the trails in Arizona

turns out that California was once underwater and the mountains are just exposed sea bottom so using a water cannon to mine made quick work out of the hills

That's Funny. Since the day I was born, I was around gold. Sat on my dad's lap for as far back as I can remember as he worked on making jewelry for his clients. I ended up working for him over around high school and some during my college or when ever he got too busy.

I have no interest in gold what so ever. I was just going through videos of a place called Sutter's Mill in the foothills of the Sierra where they discovered gold back in the middle 1800s. I like to visit this winter, maybe? I came across this water canon from one of the videos and was thinking how the heck they get the energy or pumps from way back to drive that much water through these canons to remove the entire hillside? I remember see them in Clint Eastwood's movies but never pay much attention on how they worked.

From there, I also read about the Orential Mining Company associated with Australia. I had no idea the Chinese were in Australia mining gold around the same time Gold was discovered in CA. They used the same method to remove the earth to get at the gold.

I was a Geology major in my first few years of college but had a change of heart and discovered that digging in the dirt doesn't pay a lot of money. Still, I like geology. I will look for that program on U tube and check it out.

Interesting. Thanks for the link. I must watch that movie again now.

The audio starts at 35 seconds in.

Steve seems to have found the answer. I was going to mention the Hurst Castle used garvity from the adjacent mountain top to the castle through contunually smaller pipes creating the pressure.

I also found this. Fountains in Paris before pumps.

The Romans did that to feed their water systems centuries earlier.

I have pictures of my parents dating in the 1940's and they are at the Sutter's Mill replica in swim suits...there was evidentially a beach on the North or South Fork of the American at the time.

I'll see if I can find it and scan it.

Over the years as a white water rafting guide, I ran the American at least fifty times. We always stopped at Sutter's Mill and let the passengers look around....1976 to 1981.

Lastly, my Mom's side of the family owned a butcher shop in Placerville before the Gold Rush and did very well once it got started

Gravity and gradual reduction of the ID of the pipe. Kind of like a water tower.

^This.

Building aqueducts and unbelievable bridges (btw which still stand to this day) across hundreds of miles of treacherous mountain terrain everywhere in the world when laser levels were "not a thing". Every foot of wasted drop or uphill settling was a delivery loss at destination.

Many ancient structures were based on water leveling for creating their foundations.
There were advanced pyramids in S. America, India, SE Asia, and all over the world.
