THEUST OT THE SCEEWS. 



The net power applied to the propulsion of the hull by the two pro- 

 pellers, being 289.642 horses, is equal to (289.^42x33,000=) 9,558,186 

 foot-pounds of work per minute, and, the speed being 10.03 knots per 

 hour, is equal to ( ^^'^^g^ 6086 ^\ -^Q-^^rj^r^Q feet per minute ; therefore, 

 the resistance of the hull (and the equivalent thrust of the screws) at 



^ 9,558,186 \ n onrc A 



that speed was ( -TTjTyV-g = ) 9,395 pounds. 



^ r 9395 \ 



The thrust per indicated horse-power, at that speed, was (^^ 457 526 ~ / 



/- 9395 \^^^ 

 20.31 pounds, and per pound of coal per hour it was ( ioi6 97 ~y 



pounds.
