PLUMBER AND STEAMFITTER May 20, 1908 Determining Amount of Radiating Surfaces Simplified Methods of Estimating Radiation—Another Article on This Subject Written for the Plumber and Steam- fitter by C. E. Oldacre, Toronto. Ill the proportioning of radiating sur-faces for large buildings or spaces a?greater variation of conditions is metwith than in small buildings or privatehouses. These variations may be in regard totliL- temperature required, the constancyof the heating, the amount of exposure,tlic amount of glass surface, the relationof the exposed glass and wall surfaceto the cubical contents, the space oc-cupied by the contained goods and ma-chinery, tlie thickness of the walls, thekind of walls or the number of floorsof the building which may require heat-ing- In such cases tlie radiation can not beproportioned with any certainty ofsuit 30x100 feet and 10 feet high. The onlyexposed walls are the two front and rearwalls. It is to be assumed that thereare buildings on each side
