She's a class H. boat built last year oil fuel turbines runs up to thirty knots and she's doing 'em, too, just now! Come on, Copplestone more stuff on this fire!" "I don't think we need be uneasy," said Copplestone. "Miss Greyle thinks that her mother will have raised a hue and cry after the Pike. This torpedo thing is probably looking round for us. She what's that?"

Draining as it does the great lakes of the interior, which have a total area of 92,000 square miles, with an aggregate basin of 290,000 square miles, the volume of water in the Niagara River passing over the cataract every second is something like 300,000 cubic feet; and this, with a fall of 276 feet from the head of the upper rapids to the whirlpool rapids below, is equivalent to about nine million, or, allowing for waste in the turbines, say, seven million horse- power.

For the present the power was produced by a steam engine at Portrush, giving motion to a shunt-wound dynamo of 15,000 watts=20 horse power, but arrangements were in progress to utilize a waterfall of ample power near Bush Mills, by means of three turbines of 40 horse power each, now in course of erection.

Just as in turbines a combination of impact and reaction produces the maximum practical result, so in screw propellers does a corresponding gain accompany the same construction. Turbines.

Consequently, in the case of turbines equipped with barometric or jet condensers, it is often thought sufficient to rely upon the measurement taken of the boiler feed, and the boiler's initial and final contents.

He was the rack-tender it was his task to keep the ribs of the guarding rack clear of the refuse that came swirling down with the water, for flotsam, if allowed to lodge, might filch some of the jealously guarded power away from the mighty turbines which growled and grunted in the depths of the wheel-pits.

In a second he had swung himself down over the scaffolding, alighting on a sawdust heap. "Hold back the deals!" he yelled in a voice that pierced the din. It was not five seconds ere every one in the mill seemed to know what had happened. Two men sprang on the slides and checked the stream of deals. Then the great turbines ceased to grumble, and all the clamor of the saws was hushed.

I have misjudged you, Mr. Cary; I thought you little better than a fool, but that story here of a collision in a fog and the list of damaged Queen Elizabeths in dock would have taken in even me. Fritz will suck it down like cream. I like that effort even better than your grave comments on damaged turbines and worn-out gun tubes. You are a genius, Mr.

"There was a fool of a night watchman at the power plant I reckon he thought I was going to steal the turbines, but he finally let me in, and I set him to starting up the power while I cleaned up Murphy's job and put in the new rope." "All by yourself?" asked Peterson. "Sure thing. Then I got her going and she worked smooth as grease.

Tom took over the hydrophones. Sure enough, his ears could make out the faint hum of the jetmarine's atomic turbines. Tom directed Hank toward the sound, then ordered him to switch on the Sea Hound's powerful search beam. The light cut a path of radiance through the murky dark-green waters. Dead ahead, the jetmarine could be seen gliding across their field of view.
