needed, both in the way of information 

 and equipment. 



If water is to be obtained from a 

 community ditch, the determination of 

 the expense offers no special difficul- 

 ties, but if a private pumping plant is to 

 be established, a careful determination 

 of costs is needed in making up a pre- 

 liminary estimate. Fluctuations in price 

 of materials, especially high under pres- 

 ent war influences, necessitates individ- 

 ual calculations. Some help to a deter- 

 mination of what is needed may be 

 gathered from the following data com- 



SULPHUR

 so recommended by the 

 University of California 

 that If you sulptiur your 

 grape vines and orchards 

 6 times they will not be 

 affected by MILDEW or

piled from reliable sources (largely 

 from University of California Circular 

 No. 117): 



Items entering into the installation of 

 a pumping plant are determined by the 

 source of water supply. The simplest 

 cases comprise the use of a suction pipe 

 extending into a surface supply, as a 

 river or lake. When underground water 

 is the source, provision for one or more 

 wells must be made. A plant under 

 such conditions requires an engine, 

 pump, suction pipe, check valve, hand 

 pump for priming, outlet pipe, connec- 

 tions for engine to pumphouse, possibly 

 an engine pit (if lift is more than 

 twenty feet), well casing, and possibly 

 sand point or gravel screen. Care in 

 determining the best method of instal- 

 lation and the best equipment for the 

 local conditions will always pay. To 

 the cost of the various items must be 

 added the expense of drilling wells, 

 cost of installation, and providing for 

 protection. An idea of the size of plant 

 needed is gained by calculating the 

 amount of water needed and the time 

 limits available for applying it. For 

 instance, if a certain orchard of twenty 

 acres must have three irrigations of six 

 inches each during the season, the water 

 to be applied in ten days of ten hours, 

 and estimating the six inches to be 

 enough to include ditch leakage, a plant 

 must be available having a sufficient 

 head to deliver one acre foot every ten 

 hours, or one and a quarter cubic feet 

 per second when figured according to 

 the following rules: 



1 acre foot of wafer equals 43,560 cubic feet. 



1 cubic foot of water equals IVi gallons. 



1 second foot of water equals a flow of one 



cubic foot per second (sometimes called one 



second foot). 

 t cubic foot per second will cover two acres 



approximately one foot deep in 24 hours. 

 1 cubic foot per second is equivalent to a ilow 



of 450 V. S. gallons per minute. 

 1 miner's inch equals 10 U. S. gallons per 



minute. 



As a basis of figuring, if local rates 

 are not available, the cost of drilling 



February 



wells should not exceed about $1.25 per 

 foot for the first fifty feet, -$1.50 for the 

 next fifty, and an increase from then on 

 of 25 cents per foot for each additional 

 twenty-five feet in depth. This for a 

 10 or 12-inch well. 



The size of pump, measured in U. S. 

 gallons per minute, needed to give a 

 six-inch depth of water on selected 

 acreages when operated for periods as 

 given, is: 



Time available Acreage to Be Covered 



for pump— 5 Acres 10 Acres M Acres 



5 days of 24 hours.. 113 225 900 



10 days of 24 hours.. 56 113 450 



20 days of 24 hours. . 28 56 ^ii> 



Note that 10 days of 12 hours each is equiva- 

 lent to 5 days of 24 hours; 20 days of 12 hours 

 each to 10 days of 24 hours, and so on. 



Of the several kinds of pumps, the 

 centrifugal is most extensively used, 

 both horizontal and vertical types, and 

 generally prove satisfactory for total 

 lifts of not to exceed fifty to seventy- 

 five feet, the lower lift being the limit 

 for the smaller sizes. Plunger pumps 

 are used when supply is near the sur- 

 face of the ground and the lift to de- 

 livery is high — over seventy-five feet. 

 Other types, as deep air and air lift 

 pumps, are used under special condi- 

 tions of high lift. 



The size of a centrifugal pump is 

 rated according to the diameter of the 

 discharge in inches. Ratings vary some- 

 what in actual practice, but for general 

 purposes will deliver about:

In the project given above, a six-inch 

 pump would therefore be required. 

 The size of engine needed to pull a 

 given pump depends not only on the 

 size of the pump and type of engine.
