Brainiac Needed

[Fla._Deadheader]

 I am somewhat familiar with Rife Ram Water Pumps. I know they will produce 6-7' up lift, for every 1' of water supply head.

  My project, if I choose to accept it, is, I want to pump water uphill to keep a pond full. I have a nice flow of water across our place, but, I don't know how to measure the height I need to push the water. There HAS to be a point where the water will not go any higher.

  I need to measure the height, from the water, to the top of the hill. There are trees that I could sight off of, with a carpenters level, to get a TOP height.

  HOW do I measure to that same height from the water level

Do you have a hose long enough? Fill a hose at the pond level, and put a pressure gauge at the source level. Devide pressure by .434 that will give you head in feet.

You need a range pole  and a spot to take readings from with the level.  A laser would make it a lot easier.  
Get an old aermotor windmill and a sealed piston pump and then you only have to figure how long the hose has to be.
 Thats about the end of my brainy acts

 Figuring head is easy. It's up that hill that's difficult.  ::)Must be 100' or more

  Just need to KNOW. 

  AHHHhhhhhh. Just re-read your post.  Not near enough hose, to reach down the hill to the water level.

  Don, no wind where I need the pump.

I like Don's idea.  Use a pole instead of tree to siight against.  You won't be able to do it all in one sighting, but you can measure the level on the pole if you move every 20 feet or so. Just move you to the site of the place the pole was,  have someone move it ahead 20 paces and shoot it again.  Keep adding the heights together till you get to the stream.

Here is a link to a simple trig calculator site.

You can plug in the hypotenuse (straight distance to the pond, parallel to the ground) and then measure the angle from vertical. It will give you the vertical distance.

 This is a steep hill. I can run a 100 foot steel tape from the pond site, down the hill. I need to know the height of the hill. That would need to be stretching the tape straight out, into thin air, NO    That's why I asked. If I'm not thinking straight, educate me 

  I've been thinking, how do I measure the height of a tree, that's very near the PUMP site

I think I remember hearing of a ram in China that pumped a trickle up 3000'

[Fla._Deadheader]

  OK. I've been there. Without the instruments, how do you figure the angle

  I'm thinking there is a stick kinda thing, that a Forester can use, to gauge the height of a tree. Can't remember it's name or where I saw one described

Wanted - old Boy Scout that still has his memory

FWIW  - I recall some way that a Boy Scout could measure something standing up by using a pencil. Let's chose a tree as an example. You stand off from what you want measure and pick a spot ( lets call it A )  at the bottom of the tree. You line up the pencil vertically with the spot on the bottom and note ( or mark ) where the top of the tree hits the pencil ( spot B ) . Then - keeping the distance to the tree the same - you move the pencil so its horizontal with the tree ( makes a 90 degree angle ) and line up that bottom spot ( A ) again. This time the mark a new spot ( spot C ) along the ground where the mark on the pencil for the top of the tree was ( spot B ) . Now measure ( with a tape or pace it off or  . . . ) from the bottom of the tree ( spot A ) to the spot marked by the pencil ( spot C ) and you've got it.

Now a mind is a terrible thing to waste and I simply can't recall if I got all that right or in a way that makes sense.

A surveyor's transom would be the easiest way, but I think you could build one as well. Use a protractor, a plumb bob, a level, tripod, and a sighting board. Mount the board to something like a tripod with a way to pivot it and hold it level. Use the level to set the plumb bob string to 0 degrees on the protractor that is mounted to the board. Tilt the board back and sight up to the top of the hill. Read the angle from the plumb bob string on the protractor. Now you have the hypotenuse and one angle. The plug in calculator will now give you the vertical leg of the triangle.

DanG, I type too slow 
protractor and a coupla straight edges?

No protractor, use a compass, make equidistant bisects along an arc on a piece of cardboard, label degrees and make one.

Hmmm, get fancy nail it by the arc's pivot to a walking stick. Hang a string and bob, tape a tube to the bottom straight surface of the protractor. Hang a level pointer off the stick at the pivot of the arc. Hold stick plumb, sight thru tube, swing to sight top and record degrees  .

[logwalker]

Read the angle from the plumb bob string on the protractor. Now you have the hypotenuse and one angle. The plug in calculator will now give you the vertical leg of the triangle.

Forgive if I am wrong, but all I see here is you have an angle. That horizontal leg is not too easy to measure. Did you have a way to measure the length of the hypotenuse? Joe

Do you have a hose long enough? Fill a hose at the pond level, and put a pressure gauge at the source level. Devide pressure by .434 that will give you head in feet.

Dave has the right solution. You have to run a hose up there anyway. Done deal. Joe

[Don P]

Alot to be said for that.

Try this:

Find a smaller triangle that is the same proportion as the larger triangle.

The larger triangle would be from the lake to the stream.  Call the hypotonuse H1 (direct line of sight from the stream to the pond on an upward angle) and the vertical leg Y1.  You want to find Y1 and it sounds like you can measure H1.

Determine a small triangle that you can measure.  Drive an 8' stake in the ground so that the top will be exactly in the same line of sight from the stream to the pond or line H1.  Have someone help you measure from your eye to the top of the stake and call that H2.   Then use a 4' level or pocket surveyors level to sight a point on the stake.   Measure from that spot on the stake to the top and that will be Y2.

Proportionally  H2/Y2 = H1/Y1   

To solve that equation simply cross multiply:  H2(Y1) = Y2(H1)   

Isolate Y1 by taking Y2(H1)/H2 = Y1

You can get fairy accurate readings with a GPS over a 15 minute to 24 hour (more accurate) reading by taking averages at the lowest and highest point.   Call the manufacturer for best method.

I could do it now Mr. Harold.  I wish I was in there in the shape I am now then the shape I was then. I'm 20 years younger.
