Page 203 - England it is customary to define a heat unit as the quantity of heat that is required to raise the temperature of a pound of water 1° on the Fahrenheit scale.
Page 253 - L of energy of the heat communicated; and that a corresponding machine, or the same machine worked backwards, may be employed to produce cooling effects requiring about the same expenditure of energy in working it to cool the same substance through a similar range of temperature. When a body is heated by such means about...

The sides and top of the stove are thus converted into a hot chamber, offering an extensive surface of heated metal ; at the bottom, by an opening in the ornamental part, the air is allowed to enter, and rises as it becomes warmed, traversing in its ascent the different compartments formed by the hot parallel plates, and is allowed to escape at the top by some similar opening into the room.
Page 98 - The nature (age) of the peat, its consequent density, &c., must direct the burner. A mound, of the circumference stated, produced from not quite air-dried peat, 24 per cent. of the weight and 27 of the bulk ; from air-dried, 27 per cent. in weight and 32£ in volume ; from freshly dug Pfungstadt peat, 30 per cent. in weight and 29 in bulk; from excellent peat, quite dry, 35£ of the weight and 49 per cent. of the bulk. In the district of Siegen very good peat produced 23 per cent. of the weight and...
