APPROXIMATE COST OF FUEL REQUIRED TO PUMP 1,000 GALLONS OF 

 WATER PER MINUTE, FOR VARIOUS LIFTS : 



Note. 1,000 gallons of water per minute 

 equivalent to two acre feet of water. 



The accompanying table gives an 

 estimate of approximate cost for fuel 

 and maintenance of a pumping plant 

 having a capacity of 1,000 gallons of 

 water per minute for total lifts of ten, 

 twenty and thirty feet. 



In order to determine approximate- 

 ly the cost of pumping water any dis- 

 tance between twenty and thirty feet, 

 a proportional part of the cost for ten 

 feet can be added to the cost for twen- 

 ty feet. Thus, to get the cost of pump- 

 ing water a distance of 25 feet, half 

 the numbers in the first line of the 

 table can be added to those in the sec- 

 ond line. The table should only be 

 used for estimating the cost of pump- 

 ing water for lifts lying between twen- 

 ty and thirty feet. The cost for ten 

 feet is given for the purpose of mak- 

 ing estimates, but it should not be sup- 

 posed that the cost for this low lift 

 would be merely half of that for the 

 twenty foot lift, as friction losses and 

 others would tend to make the cost for 

 the low lift higher than that stated in 



the table. 



FIRST COST OP PUMPING PLANTS. 



At almost any point in the river val- 

 leys of the western plains complete 

 pumping plants, including wells, ma- 

 chinery and buildings, can be con-< 

 structed for about $100 per horse pow- 

 er required. In some exceptional cases 

 the cost may run as low as $60 per 

 horse power. 



The pumping plant of Mrs. M. 

 liter, near Garden City, Kan., uses 



pumped continuously for eleven hours is 



a Menge pump which is run by a 10- 

 horse power Otto gasoline engine. The 

 area of the strainer and the bottom of 

 the well is 266.5 square feet. The spe- 

 cific capacity per foot of percolating 

 surface is .341 gallons per minute. The 

 cost of operation with gasoline at 20 

 cents per gallon amounted to 21 cents 

 per hour, .89 cents per thousand gal- 

 lons, $2.90 per acre foot, and 1-17 

 cents per thousand foot-gallons. 



The pumping plant of Nathan Ful- 

 mer, near Lakin, Kan., utilizes a chain 

 and bucket pump. The power is sup- 

 plied by a Howe gasoline engine which 

 develops about 7 horse power at 285 

 revolutions per minute. The cost of 

 gasoline at 21 cents per gallon and the 

 expense of running the engine was 

 13.65 cents per hour. The cost of 

 water was $1.37 per acre-foot, .22 

 cents per thousand gallons, and 1-40 

 cents per thousand foot-gallons. 



The pumping outfit of J. H. Logan 

 near Garden City, Kan., consists of a 

 6-horse power horizontal gasoline en- 

 gine connected by a belt to a No. 3 

 centrifugal pump. The specific ca- 

 pacity of the well is 422 gallons per 

 minute, or 3.94 gallons for each square 

 foot of well strainer. The fuel cost of 

 pumping was .9 cents per thousand 

 gallons, $2.93 per acre-foot, or 1-25 

 cents per thousand foot-gallons. 



The cost of pumping at 12 plants in 

 the Arkansas Valley in Western Kan- 

 sas ranged from $0.85 to $3.75 acre- 

 foot.
