Further than this it cannot go because air-valves are necessary just beyond
the summit which would render any syphon arrangement impossible.
Taking a 6" pipe loss by friction to top of ist ridge—159/
Height to be pumped is i,ico + 159 = 1,259 (In 5" pipe loss by friction =
412' which will make pressure too high for pumping) H. P. required—*0023
H. Q.
= 1,259 X 22*5 = *0023 =65 = H. P.
To pump the water over the 2nd ridge and right to the Oil Fields would
require the same sized pipe and only 7 more H. P.—head being 1,416/
It therefore appears that it is well worth while to carry t e water right on
to the Fields.
A simple scheme would be—
At Debra Kasinieh or at nearest point of river (it is immaterial which, as
the difference in frictional head is minute) a pumping station containing—
^—50 H. P. Cochran boilers (includes 1 spare).
2—5,000 gallon Worthington Compound Duplex Pumps with externally
packed plungers for gritty water (includes one spare).
A small boiler water condensing set to save boilers 26 miles of 6".steel pipe
to take 750 lbs. pressure per sq. in.
Seven miles of oil line pipe for fuel to engines to stand 700 lbs.
pressure.
One oil fuel storage tank.
Water storage tanks would be required at—
ist ridge ^
Libari Plain each to contain 200,000 gallons.
2nd ridge J
At the Oil Fields storage for 1,000,000 gallons.
Storage tanks could be of iron but would have to be surrounded by thick
bank of earth to prevent perforation by bullets.
These calculations, etc., could be checked by the Oil Company’s Consulting
Engineers in England who have full knowledge of the local conditions and
also copies of plans, sections, etc.
