Page 24 - It must he distinctly understood that the extent of heating surface found in this way offsets only the windows and other cooling surfaces it is figured against, and does not provide for cold air admitted around loose windows or between the boarding of poorly constructed wooden houses. These latter conditions, when they exist, must be provided for by additional heating surface. EXAMPLE 1.
Page 24 - Divide the difference in temperature, between that at which the room is to be kept and the coldest outside atmosphere, by the difference between the temperature of the steam pipes and that at which you wish to keep the room, and the product will be the square feet, or fraction thereof of plate or pipe surface to each square foot of glass (or its equivalent in wall surface).
Page 153 - In order to effect this, the pipe is wound about first with asbestos, followed by hair felting, porous paper, manilla paper, finally thin strips of wood laid on lengthwise, and the whole fastened together by a copper wire wound spirally over all. This is thrust into a wooden log, bored to leave an intervening air chamber between the pipe and the wood, and of sufficient size to leave from 3 in.

It will be seen by a study of the table that the average value per acre of all farm lands In the manufacturing section in 1900 was, according to the census, $24 per acre, and in the non-manufacturing...
Page 43 - ... require great care; for should the boiler have an automatic water feeder set for the true water line, it will fill up, but cannot discharge again when the steam goes down ; while, if it has no feeder, there is danger of spoiling the boiler, as the water is in the pipes in the form of steam.
Page 140 - XVIII. AIR. Air is a mixture whose parts are not chemically combined, consisting of about 77 per cent, of nitrogen and 23 per cent, of oxygen, by weight, when considered pure, ie, when it is in the condition best suited to support animal life. It also contains from about ^ 0 jj 0 0.

When steam or vapor is condensed, this same quantity of heat that was received, no matter where, is again given off to any substance within its influence, air, water, etc., colder than itself; and it is this property, to convey more heat within ordinary controllable temperatures than any other substance which makes water and its vapor so valuable...
Page 144 - ... the proportion depending on the temperature of the air. The warmer it is, the larger quantity it will hold, and as it becomes cool again, it deposits it, or forms clouds or fog, which condense on anything colder than the air; leaving the air upon raising its temperature, capable of taking up more moisture, to be again deposited in dew or rain. It is this property of air which gives it its drying qualities.
Page 156 - The departing pipe is immovably attached to the box, so that one end of each 100 feet of pipe is fast, and the other movable — affording free play to the expansion and contraction. All service-pipes are taken from the junction-box, which is securely bolted to the masonry and anchored to the pipes. The bottom of the box, being placed lower than the pipes, all water of condensation is carried forward and deposited in it ; the arrangements for the escape of the condensed water from the steam pipes...
