Page 18 - ... they leave the room, but by drawing on the blackboard before their eyes, or by setting the students themselves to draw, the geometric figures which they may hereafter need to construct in real work. Neatness and care in drawing geometrical figures- should be impressed upon the students;, the object c of such practice is to secure accuracy, which can only be attained by precision in practice. Take one easy problem, viz. to bisect a straight line. Here we have a diagram, and the directions : "...
Page 141 - Weisbach's formula, of 298 feet per minute in 4-inch diameter pipe flowing full or half full ; 1 in 60 = 279 feet, in 6-inch pipe; 1 in 100 = 264 feet, in 9-inch pipe; 1 in 250 = 213 feet, in 15-inch pipe; 1 in 300 = 213 feet, in 18-inch pipe. To obtain a velocity of three feet per second in circular sewers the following falls should be given, according to the same formula : — 15 in. 18 in. 21 in. 24 in. 30 in. 36 in.
Page 84 - ... particles or atoms of any substance are caused to move round and round each other,' or backwards and forwards with increased velocity, heat increases in proportion to the velocity of the movement and impact of the atoms. Heat is measured in this country by a standard unit, viz. the amount of heat required to raise the temperature of a pound of water at 32° one degree Fahrenheit. The standard English unit for the measurement of work is the work done in raising one pound weight vertically one...
Page 451 - It is also contained in small quantities in galena (p. 210), and it can be extracted with profit from the lead prepared from this ore, even when the lead contains only two or three ounces of silver to the ton. The method thus adopted for the extraction of the silver depends upon the fact that the whole of the silver can be concentrated into a small portion of lead, by crystallization; metallic lead free from silver separates out in crystals, and a rich alloy is left. When this reaches the concentration...
