What Horse Power Means.

Very few people realize just what a horse power, as expressed in engineering terms, really means. When it is stated that the world’s largest Curtis steam turbine, -which drives an electric generator in the Waterside station, New York, develops 30,000 horse power the meaning is vague and incomprehensible. Imagine this term reduced to man power and almost every one can grasp its full meaning. If it takes twelve men to equal one horse power then this mammoth turbine engine develops 12 times 30,000, or the working energy of 360,000 men. If these men worked in eight-hour shifts each day It would require the services of 1,080,000 men every twenty-four ’’hours to produce the working energy of this turbine unit.; —Electric News.
