Page 90 - Measures of Length 10 millimeters (mm.) = 1 centimeter (cm.) 10 centimeters = 1 decimeter (dm.) 10 decimeters = 1 meter (m.) 10 meters = 1 dekameter (Dm.) 10 dekameters = 1 hektometer (Hm.) 10 hektometers = 1 kilometer (Km.) 10 kilometers = 1 myriameter (Mm.) Measures of Surface 100 sq.
Page 4 - The heat which is expended in changing a body from the solid to the liquid state, or from the liquid to the gaseous state, is called latent heat.
Page 18 - CALORIE is the amount of heat required to raise the temperature of one kilogram of water one degree centigrade.
Page 31 - To find the piston speed of an engine, multiply the stroke in inches by the number of revolutions per minute and divide the product by 6. EXAMPLE. — An engine with a 52-inch stroke runs at a speed of 66 revolutions per minute.
Page 55 - A^tSbSt(or 3AgtS+SbtSl) = sulphur 17. 7$, antimony 22.5$, silver 59.8$. BB on charcoal, fuses with spurting to a globule, gives off antimonous fumes, and coats the coal white; with soda on charcoal, in the OF, or by prolonged heating without fluxes in the RF, gives a globule of silver. In the closed tube, gives a reddish sublimate of antimonous sulphide; in the open tube, gives sulphurous fumes and a white sublimate of antimonous oxide. In some varieties arsenic is present, in which case it can be...
Page 29 - Properties. — Hydrogen is a colorless, odorless, and tasteless gas. It is the lightest matter known, being 14.43 times lighter than air and 11,000 times lighter than water. Its molecular weight is therefore smaller than that of any other known substance. Its refractive power on light is remarkable, being 6.614 times that of air. It is soluble to a very slight extent in water, 100 volumes of which dissolve but 1£ volumes of hydrogen.
Page 9 - ... the ratio of the ovendry weight of a sample to the weight of a volume of water equal to the volume of the sample at some specific moisture content, as green, air-dry, or ovendry.
Page 54 - C., yielding a vapor whose density is 198 instead of 99. This would indicate that the vitreous modification which is formed at high temperatures has the molecular formula AstOt, double that of the octahedral modification.
Page 44 - This includes, in the case of the multitubular boiler, the portions of the shell below the line of brickwork, the exposed heads of the shell, and the interior surface of the tubes. In the case of a water-tube boiler, the heating surface comprises the portion of the shell below the brickwork, the outer surface of the headers, and outer surface of tubes.
