70 SECOND THOUSAND QUESTIONS IN AGRICULTURE 



of stove distillate an hour at the rate of less than 5 cents a gallon. This 

 would allow a run of twelve hours for 30 cents. Gasoline at 15 cents a 

 gallon would bring it up to 90 cents. A motor of the same horsepower 

 would cost about $70 and use about 4 KWH of power an hour. At a 

 power rate of 3 cents a KWH a twelve-hour run would cost $1.44. In 

 the case of a 100-foot lift, one would prefer a 15 horsepower gas engine 

 or motor and a No. 3 vertical centrifugal pump, two stage. The engine 

 would cost up to $640 and would use two gallons of stove distillate per 

 hour at 5 cents. Thus a twelve-hour run would cost $1.20. A motor of 

 the same size would cost $190 and would use 11 KWH an hour. At an 

 average of 2^c a KWH a twelve-hour run would cost $3.30. Though the 

 motor costs a great deal less in the beginning one should study the 

 local power rate schedule and figure on the cost of operation as time 

 goes on. The approximate costs of the two lifts are as follows : 



30-Foot Lift 



Pump $100 Pump $100 



Engine 350 Motor 70 



Pipe 15 Pipe 15 



$465 $185 



100-Foot Lift 



Pump $330 Pump $330 



Engine 640 Motor 190 



Pipe 50 Pipe 50 



$1,020 $570 



So we are impressed with the fact that the lift and equipment chosen 

 have a great deal to do with the installation, to say nothing of the cost 

 of maintenance and operation. Holter & Rogers. 



Pumping for Alfalfa. 



Is it possible to pump water 100 feet for alfalfa and make a good 

 profit, when alfalfa will sell for $10 per ton or upward? Water is in 

 abundant supply. From one well a How of from 1,000 to 1,500 gallons 

 per minute can be secured. 



With the cheap fuel engines now on the market the fuel cost is 

 comparatively low. Take a crude oil engine that is said to burn oil of 

 as low as 24 degrees gravity. We wish to pump 1,200 gallons per minute. 

 This will require a No. 7 pump. To raise this amount of water a dis- 

 tance of 100 feet a 75* horsepower crude oil engine will be needed. This 

 engine consumes, say, from 9 to 10 gallons of fuel per hour at from 2 

 to 3 cents a gallon. Take the higher figure and the fuel cost will be 30 

 cents an hour or $3.60 for a 12-hour run. The water will cover 3J4 acres 

 6 inches deep. Practically a cost of $1.00 for each 6-inch irrigation, or 

 $5.00 an acre for a 30-inch irrigation for the season. Cost of attendance
