A manual of heating and ventilation, in their practical application, for the use of engineers and architectsEmbracing a series of tables and formulas for dimensions of heating flow and return pipes, for steam and hot water boilers, flues, etc., etc . surrounding walls and solid objects absorbing a certain amcjuntof radiant heat and again heating the air by contact. Radiant heat does not heat the air through which it passes,to any appreciable extent. The intensity of heat emitted by a plane surface, decreaseswith the sine of the angle formed between the direction of therays, and the surface at the point of emission; therefore circularsurfaces are more effectual than plane ones. GENERAL PRINCIPLES. INDIRECT RADIATION. In indirect radiation, the coils crradiators are placed in other roomsthan those they are intended to heat,generally the basement or cellar as atR, the fresh air being conveyed tothem through flues or ducts F, andheated by contact, and thencethrough flues or ducts F„ into thevarious rooms; the quantity of coldair being regulated by dampers walls and solid objects in therooms are heated by contact with thewarmed air
