THE IEKIGATION AGE. 



As a general rule, it is impractical to pipe across an open 

 stream, unless absolutely necessary, on account of flood con- 

 ditions, cost of foundations, etc. Unless this could be done, 

 the pumping must be divided. However, the details in regard 

 to the possibility of piping across the river are riot at hand. 

 We assume, in the absence of further information, that sepa- 

 rate provision will be made for each side of the river, calling 

 for at least two pumping outfits; of these the one for the 

 east side would be the larger. 



As to size of pump to use, Mr. Cantelou speaks of having 

 a No. 10 Gould centrifugal pump with a 30 H. P. Gasoline on 

 another plat, further down the river, irrigating alfalfa. This 

 seems to suit him as to size pretty well. 



However, in view of the necessity of having at least two 

 pumping outfits for this land, we would suggest the use of a 

 No. 8 Morris Centrifugal pump for the east side of the river 

 and a No. 6 for the west side. The No. 8 Morris Centrifugal 

 pump operating at its normal capacity of 2,000 gallons per 

 minute, would cover in 10 hours, one inch deep, a theoretical 

 area of 44 acres; the No. 6, at 1,000 gallons per minute, 22 

 acres. These figures do not include waste, percolation, seep- 

 age, evaporation, etc. 



The location of the pumping outfits ought to be carefully 

 considered. 



In order to operate most economically, the pumping 

 should be done where the elevation to be overcome will be 

 the least possible, and still deliver the water where needed. 

 This brings into account the relative elevations of the stream, 

 and the profile of the land surrounding it. We suspect there 

 is a gradual drop in the land from the north line southward, 

 which leads to the question, as to whether it would not be 

 better to move the pumping plant southward as far as pos- 

 sible. There appears to be a good point about J4-mile south 

 of the north line, indicated by the letter A, where the river 

 begins to make a wide bend. 



To overcome the rise in the land north of this point, have 

 the banks of the ditches raised sufficiently so that the water 

 will be carried north as far as wanted. Suitable gating ar- 

 rangements can be provided at the pump discharge so that 

 the water will be forced north when needed. Then when 

 pumping for points south of this, which would cover perhaps 

 two-thirds of the land, the lift would be several feet less and 

 the work done with that much better economy. If three or 

 four feet could be taken off the pumping head by this means, 

 it would save from one-fourth to one-third in the cost of 

 fuel for that particular service. 



Mr. Cantelou asks about a portable outfit. A portable 

 outfit properly located will do the same work with greater 

 economy because it can be located at the point where the 

 pumping head is the least. It can also serve portions which 

 would otherwise not be thoroughly irrigated, and would make 

 the problem of ditching and cleaning ditches easier. Besides 

 this it can be used for other purposes. It would undoubtedly 

 be a good investment. 



A portable outfit with a No. 6 pump could serve the small 

 western portion of the land and then be moved across the 

 river to help out the No. 8. The two combined would have 

 the same normal capacity as a No. 10, with the advantage of 

 better distribution of water. 



We think that Mr. Cantelou should use one No. 8 Mor- 

 ris Centrifugal pump, stationary, and one No. 6 Morris pump 

 as a portable outfit on trucks, or else that he should use three 

 stationary outfits, consisting of one No. 8 and two No. 6 

 pumps, with engines for each. The additional stationary out- 

 fit to be so located as to serve the farther portion of the east 

 side of the river where the lift is probably low, and where 

 the water would not be required to flow through such a large 

 amount of ditching. 



The No. 8 Morris Improved Standard Horizontal Right 

 Hand Centrifugal pump, with belt pulley and hand primer, 

 should be used for the main stationary outfit in either case. 

 It has 8-inch discharge and 10-inch suction connections, 

 weighs 2,430 pounds and has 20x12 pulley. The speed on 15 

 foot total head, including friction allowance through piping, 

 is 250 revolutions per minute ; on 20 foot head 293 revolutions 

 per minute. 



10-inch piping should be used on both suction and dis- 

 charge. This will make pumping conditions easier. It also 



The Primer of Hydraulics is Now Ready 



has the additional advantage of making it possible to inter- 

 change piping at any time. 



In order to understand this No. 8 Morris pump properly 

 would say that the shell is about the same or larger than 

 the Gould No. 10, which Mr. Cantelou has and contains 

 about the same amount of metal in its vital parts. No. doubt 

 Mr. Cantelou would consider it another No. 10 pump. It 

 has the enclosed runner or piston which wears better than the 

 "open" wing pumping dirty or gritty water, which is usual in 

 irrigation streams. The runner is large, with large water- 

 ways, thereby causing it to operate at slower speeds, and with 

 less mechanical toubles than is usual. The "enclosed" runner 

 usually maintains efficiency better, i. e., after prolonged serv- 

 ice, the effect of wear is less. 



To operate this pump we suggest a 25 H. P. Venn-Sev- 

 erin kerosene or fuel oil engine with belt pulley. This engine 

 will provide a considerable margin of power, of which full 

 use may be made. The normal speed delivering 25 H. P. is 

 about 275 revolutions per minute. If the pulleys are so pro- 

 portioned that the pump will run at catalogued speed for the 

 head, when the engine is running about 230 revolutions, there 

 will be 45 revolutions per minute of increase, which may be 

 added by adjusting the governor springs. By increasing the 

 speed of the pump and engine, from 30 to 50 per cent may be 

 added to the capacity of the pump if needed, and this should 

 require about the full power of the engine. This is the way 

 to get good service from this outfit. 



The price of the above pump and engine, f. o. b. cars 

 Chicago, is estimated at $983.50. 



If the pumping plant can be so arranged that the actual 

 pumping head, including friction, is between 15 and 16 feet, 

 then a No. 10 Morris Centrifugal pump could be used ca- 

 pacity 3,000 gallons per minute which would make the outfit 

 cost about $40 more. 12-inch piping should be used on both 

 suction and discharge. 



12-inch rubber belting, 4-ply, of the best quality, known 

 as "Extra" (sold with a guarantee), for No. 6, No. 8, or No. 

 10 pumps costs 76 cents per foot. If made endless, 3 feet is 

 added for splicing. On account of the long running hours, 

 only the best belting should be used. 



It is often preferred to have a directly connected outfit. 

 It would be practical here to have the No. 8 Morris pump 

 directly connected to the 25 H. P. kerosene engine, having 

 both placed on the same base, and connected on the same 

 shaft, doing away with belting, and making the outfit more 

 compact (see appended illustration). The pumping head in 

 this case would be fixed by the speed of the engine. At 275 

 revolutions per minute the outfit would operate against about 

 W/i foot head. 



The cost of this direct connected outfit, f. o. b. cars Chi- 

 cago, is $985.00. 



Regarding the No. 6 Stationary outfit, this would include 

 a Morris centrifugal pump, with hand primer, as per ap- 

 pended cut, 6-inch discharge, 8-inch suction, which, under 15 

 foot total head, runs 295 revolutions per minute, and under 

 20 foot 341 revolutions per minute, and has 15x12 belt pulley. 

 8-inch piping should be used on both suction and discharge. 

 Pump weighs about 1,345 pounds. 



To operate this pump we suggest a 10 H. P. Venn-Severin 



Morris Centrifugal Pump Directly Connected to Engine.
