So when I proposed that the horsepower should be increased by 33 per cent., and made equivalent to 1,000 watts, I was not at all sorry to find that I had incurred the displeasure of the leader writers in nearly all our scientific papers, and I was quite sure that the attention of those who would not perhaps have thought of it would thereby be drawn to the matter.
The Cunarder Canada was in port, 250 feet long, of 2000 horsepower, and with a speed of eleven knots an hour. Everywhere we encountered the New York policemen who had taken the place of the night-watch of 1833. They were all in uniform too. They had made a fight against the uniforms, upon the principle that all men are free and equal, and that they would not be liveried lackeys.
"Nevertheless, it can generate a billion horsepower. But you couldn't get the power away if you did generate it." He turned toward Arcot, and called to him. "Arcot set it down and let her rip on about half a million horsepower for a second or so. Air arc. Won't hurt it she's made of lux and relux." Arcot grinned, and set it on the ground. "Make an awful hole in the ground." "Oh go ahead.
No doubt it might kill itself with much facility in various ways, for fifty horsepower, properly applied, would do for an elephant, much more a dog. But I don't believe that power to be sufficient to produce annihilation. There would have been remains of some sort."
Fuel consumption is 0.48lbs. of fuel per brake horse-power hour at full load, and oil consumption is 0.020 lbs. per brake horsepower hour. The dry weight of the engine, complete with propeller boss, carburettors, and induction pipes, is 850 lbs., and the gross weight in running order, with fuel and oil for six hours working, is 2,671 lbs., exclusive of cooling water.
This relation between these three constants is known as Ohm's Law and as they are very important you should memorize them. What the Watt and Kilowatt Are. Just as horsepower or H.P., is the unit of work that steam has done or can do, so the watt is the unit of work that an electric current has done or can do. To find the watts a current develops you need only to multiply the amperes by the volts.
Both steam and horsepower were used on these railways. Valleys were bridged over; gradients were reduced by every available means. At regular distances pleasant little block houses were to be found, which served as stations and guardhouses.
The Darracq firm were the leading makers of these engines in 1910; their smallest size was a 24 horsepower engine, with two cylinders each of 5.1 inches bore by 4.7 inches stroke. This engine developed its rated power at 1,500 revolutions per minute, and worked out at a weight of 5 lbs. per horse-power.
"We generate D.C. at any voltage up to fifty million, any power up to that needed to lift ten trillion men through their own height in this time a second." The power represented approximately twenty trillion horsepower. The Talsonian's face went blank with amazement as he looked at the ship. "In that tiny thing you generate such power?" he asked in amazement.
The screw propeller is 24 feet in diameter and 37 feet pitch; and the engine-shaft is 160 feet long, or 12 feet longer than the height of the Duke of York's Column. The paddles and screw, when working together at their highest pitch, exert a force equal to 11,500 horsepower, which is sufficient to drive all the cotton-mills in Manchester!
