houses. This is about twice as much as 

 a 4-inch main should supply. In fact, 

 under ordinary conditions, we would ad- 

 vise no change in the present arrange- 

 ments and would suggest the use of 

 either a 3-ineh main for each of the new 

 houses or a 4%-inch main to supply the 

 two new houses. 



Just how much radiation should be 

 supplied by a main of a given size will 

 vary not only with the length and the 

 size of the coils, but also with the 

 height of the flows and returns above 

 the top of the boiler and the ratio be- 

 tween the radiation and the glass areas. 

 The capacity of a main will be in- 

 creased if the boiler is oversize. 



If there is no glass in the side walls, 

 we judge that the radiation in the old 

 houses will keep them at from 40 to 45 

 degrees in a temperature of 10 degrees 

 below zero. By doubling the radiation 

 in the new houses, they can be kept 

 heated to a temperature of 50 to 55 

 degrees. 



SELECTION OF PIPES. 



Will you tell me how large a main 

 flow should be to supply two 3-inch and 

 two 2%-inch feed pipes which are 190 

 feet long and which are to supply eleven 

 2-inch returns, 190 feet long? 



0. B. M.— O. 



While a good deal will depend upon 

 the length of the main flow and return 

 pipes, as well as on the height of the 

 returns above the boiler, if these con- 

 ditions are fairly favorable, it would be 

 advisable to use 5-inch pipes for the 

 flow and return.
