Calculating pressure - come on in math nerds

I spent the last few minutes looking up that clip where Ogre is yelling at the Nerds on that movie, then realized there's no embedding on this site.

Another thing I rember my ex-boss talking about was a Ram. It was a gravity water pump thinger. It was shaped like a hot air balloon, water ran into it, then when it was full, a valve opened and it dumped out, pushing water down the line. Pretty cool, an early, simple water pump that needed no power.

I have one of them at my camp. They are simple to make. I have plans to assemble one for cheap if anyone's interested. A few black iron fittings and a couple of brass check valves and your on your way !

Yes yes yes I would like to have them. I've a pond next,to a creek,I want to fill.

Pete, maybe start a new thread with the directions. I'm curious too as I can't remember exactly how it works.

Remember PToombs, PJ3 is from Canada, and even their toilets spin backwards.

check out http://www.lehmans.com/. They still sell rams.

Pete, I hadn't really thought about using one. I do know that you don't need a lot of drop to make it work. Grandpa's house in PA used to have one that pumped water a 1/4 mile up and elevation of roughly 25 feet and it only had 3 foot of drop from the spring to the creek. I think the main thing with rams would be proper sizing: they work pretty slow.

Matt, lots of good info in there. I had to hunt a little, but it told the basics of how it works, how to adjust it, etc.

[PJ 3]

I guess I'm gonna have to find them and figure out how to get em posted eh ? Damm computer stuff............grrrrrrrrrr

[PToombs]

Jeez, don't stroke out about it! It's not that important, I just thought others might like to know too.

What is it with guys named Pete?

We have out houses up here.........

On second thought, I don't think a ram would work in my situation because of the rams need to pump continuously. I don't have any creeks or springs to use.

hey-Hey!!!,
The pressure drop in the pipe is due to flow friction. This friction head is equal to the height you've got the water level at. So pick the maximum or 20', that's about 10 psi... but the equations will deal in head height so it doesn't matter. account for all friction causing bits, and see what your flow will be. If it isn't enough, choose bigger pipe.
cheers,
Douglas

As long as you continue to have drop from your tank you will most likely still have flow. Your actual head will be the diffrence in elevation from your destination and the waters origin, not just the height of the tank. Also water is clingy. You can get it to flow further out of an open top pipe or trench than you can an enclosed pipe. Air offers little resistance so it allows the flow to continue even against wall friction.
