Amount of flow
your source offers can be measured fairly accurately by allowing water to
run into a bucket of known volume (e.g. a five-gallon bucket) while timing
the rate of fill accurately to the nearest second. It may be necessary to
build a small dam in the creek or spring to make it easier to catch water
to fill the bucket. Keep in mind the rate of flow from the source may be
less during drier times of the year.
Fleming Hydro-Ram needs a flow of 2-3 gallons per minute, while
a two-inch Fleming Hydro-Ram requires 3-5 gallons per minute.
Having an adequate
fall for the water from the source to the ram site is a very critical requirement.
One of the easiest methods for calculating fall is to use a carpenter's
level fastened securely to the top of a stick. (See diagram)
Starting at a proposed ram installation site, place the stick and level
on the ground and observe where the line of sight hits the ground in front.
Continue in this manner (remember to keep the device level at all times)
until you reach the level of the water source. Multiply the height of
the stick by the number of times it was moved from the ram site to water
source to obtain total water fall.
- total height to which water must be pumped from the ram site - can be
determined by the same method used to calculate vertical fall.
It has been
determined that under certain conditions the Fleming Hydro-Ram
can pump water about ten times higher than the total fall of the water
if the source has a fall of at least 5 feet, and there is adequate water
flow to run the pump, the Fleming Hydro-Ram should lift a minimum
volume of water at least 50 feet.
- lengths of drive and delivery pipe - may be determined by first calculating
the average length of one normal step. This can be done by dividing into
100 the number of steps you take in walking 100 feet. The result is an average
distance in feet per step. Multiply this figure by the steps taken between
ram and source as well as ram and delivery point to estimate lengths of
pipe needed for the system.
With a rapidly falling stream...or from a dam...it may be possible to
get a good "fall" from the source to the pump with only a minimal pipe
run. But in every case there must be a length of hard rigid pipe so as
to create a hammering effect.
