Electric Ironing
Six horsepower saws all the wood four men can pile in cords.
Twelve horsepower will drive a fifty-inch circular saw, sawing 4000 feet of oak, or 5000 feet of poplar, in a day.
Ten horsepower will run a sixteen-inch ensilage cutter and blower, and elevate the ensilage into a silo thirty feet high at the rate of seven tons per hour.
One horsepower will pump water from a well of ordinary depth in sufficient quantity to supply an ordinary farmhouse and all the buildings with water for all the ordinary uses.
In determining the size of power plant required in any particular instance the use requiring the largest amount of power must be considered. It follows that there will then be plenty of power for the smaller requirements. In considering a water power it should also be borne in mind that the full theoretical amount of a water power can never be realized, a certain portion being taken up in friction in the waterwheel and in losses in the electric generator, transmission lines, motors, etc. The question as to how much may be made available will be discussed hereinafter.
Following are descriptions of some typical water-power developments in use in this State at the present time.
