Σελίδα 164 - Multiply the square of the diameter of the cylinder in inches by the length of the stroke in inches, and by 171; and divide the product by the diameter of the driving-wheels in feet.
Σελίδα 159 - The theorem, however, is valuable to practical men, not only as being applicable to numerous other branches of mechanical inquiry, but as leading directly to the methods by which some of the best rules have been obtained for calculating the elasticity of steam, when in contact with the liquid from which it is generated. We now proceed to apply our formula to the determination of a general law, or such as will nearly represent the class of experiments on which it rests ; and for this purpose we must...
Σελίδα vi - ... in which they may afterwards be placed ; so that, with few exceptions, they continue to act wholly ignorant of the philosophical principles on which the steam-engine is constructed and applied. It has been justly said by an officer of the Royal Navy, that " whatever of dash, whatever of enterprise, whatever of combined prudence and skill is to be performed in a future war, will be performed through the agency of steam. The high, road...
Σελίδα vi - It is evident that whatever of dash, whatever of enterprise, whatever of combined prudence and skill, is to be performed in a future war will be performed through the agency of steam. The high road to distinction and fame will be found on the paddle box of a steamer, but to gain this fame, to achieve this distinction, it is indispensable that officers should add to a thorough knowledge of seamanship and gunnery, to nerve, to...
Σελίδα 162 - To find the volume or space the steam of a cubic foot of water occupies when the steam is of a given elastic force and temperature, and separated from the liquid from which it was generated, — RULE.
Σελίδα 167 - Multiply the length of the stroke of the valve by the length of the lever on the weigh shaft for the eccentric rod, and divide the product by the length of the lever which works the valve, and the quotient will be the throw required.
Σελίδα 158 - Ib., on the circular inch ; and the product by the velocity of the piston in feet per minute.
Σελίδα 149 - The area of the steam passages should be equal to the area of the cylinder, multiplied by the velocity of the piston in feet per minute, and divided by 4800. The...
Σελίδα 168 - ... proportional. The more frequently the feeding apparatus acts the less water we require, and we also see a stronger motive for using hot water for the boiler than that of barely saving fuel ; as the colder it is the more the steam will be reduced. If a boiler be fed at every stroke it should have five cubic feet of water, for each cubic foot of steam it is capable of boiling off per hour ; whether the boiler be high or low pressure.
Σελίδα 150 - ... the cooling in the cylinder and pipes 016 3. By the friction of the piston and loss •••• 125 4. By the force required to expel the steam through the passages 007 5.
