water pumping windmill question 4

[inovermyhead]

Does anyone know the formula for calculating the distance a windmill will pump horizontally?
An 8ft windmill will lift water 180ft with a 1 7/8 cylinder pump. If my static water level is 60ft and the cylinder is @75FT I'm pumping up to the surface 60 ft. I would like to know how far I can pump after that point horizontally. Surely water will move easier horizontally than vertically.
other factors that may influence distance......
1 1/2" pvc pipe at the surface only
drop pipe is 1 1/2" galvanized
I'm at 220 ft above sea level
flow of water is not constant in the pipe
thank you

inovermyhead,
I'd like to find out more information about your windmill (make, size, where you bought it, etc.) This probably isn't the forum to do that. How can I get a hold of you? Thanks.

OK, see the attached files of my setup. I used my GPS to determine that there is about a thirty foot drop from the bottom of the 1000gal poly tank to the output at the earth tank. When I first hooked it up, it would airlock every day, now, with the ck valves and timer installed it's better but I'm still not satisfied. There are two reasons for the ck valves, since it is a gravity feed system similar to a sewage drain... #1 air needs to enter the system to keep a suction from starting and creating a vacuum. #2 When my timer turns on ck valve #2 needs to close to keep water from entering my 1000 gal poly tank instead of flushing any trapped air out of the 1/4 mile pipe. All the other ck valves close at the time pressured water hits them on the way down the hill, then re-open as soon as the pump turns off. Also, if the wind didn't blow for an extended period of time I could reset my timer and allow my submersible pump to fill my water troughs and tank. I am assuming my problem starts at night when the wind quits blowing and the system drains completly. In the morning when the windmill starts to pump it does so slowly until the wind picks up, I'm assuming air gets sucked into the system and a airlock is created. The piping from the submersible pump to the windmill has been buried for about 20 years so I am unable to check for low spots there. At this time all the other pipe is laying on top of the ground and I will not bury it until I am satisfied the system is going to work. Any input would be greatly appreciated. Thank you.

Ok, sorry see the other link to file.

Don't use GPS for elevation measurements. They can be way off.

please explain why you need the "check" valves on a gravity line. there is no possibility of reverse flow, so they should not be necessary. However, looking at sketch 2, it appears they are located at water troughs. Do you somehow operate these valves to divert flow into the troughs at each pasture? The breather pipes are necessary and you need one at every high point in the line to allow air to discharge and prevent vacuum from forming. Your airlock is caused by trapped air in a high point of the line, a breather pipe should be added at all the remaining high points. A detailed profile of the pipeline created using a surveyors level (not GPS) would be beneficial to solving your problem.
