pipe will require about 2,100 feet and 

 a 6-inch flow. The 5-inch main will run 

 about seventy-five feet before it begins 

 to feed, and I expect to arrange returns 

 in the same way. This means keeping a 

 large quantity of water hot that is not 

 doing any good. D. H. McI. — Mo. 



There should be no difficulty in main- 

 taining a suitable temperature for let- 

 tuce in the 28x54-foot houses with the 

 present radiation. In fact, twelve 2-inch 

 returns should be ample. If the 5-inch 

 flow and return pipes to the 170-foot 

 house are run through one of the 28x54- 

 foot houses, it would be possible to cut 

 off several ^ore of the returns by means 

 of valves or they could be taken out, 

 provided heat will be kept up in the new 

 house at all times. 



As we figure it, if two 3-inch flows 

 and fourteen 2-inch returns are used in 

 the new house it will make only 1,800 

 square feet of radiation, if the main 

 How and return to the boiler are cov- 

 ered. This can be handled by a 5-inch 

 flow, with a return of the same size. We 

 would, however, consider the two 3-inch 

 flow pipes loaded to capacity. 



Our suggestion would be to pipe the 

 two houses as one, thus making a run 

 of 224 feet. Use the 5-inch flow as the 

 main for this house and then run three 

 .'Mnch overhead flows, with one on each 

 plate and the other below the ridge. 

 At the farther end of the house con- 

 nect each flow pipe with three 2i4-inch 

 returns. The other 28x54-fo6t house 

 may be connected with the boiler by 

 means of a 3-inch flow and return. 

 While we prefer 2iA-inch pipe for re- 

 turns in houses more than 200 feet in 

 length, if there is no other use for the 

 fourteen 2-inch returns in the 28x54- 

 foot house, they might be used for three 

 runs each 224 feet long and with seven 

 runs of a 2i^-inch pipe will furnish 

 the necessary radiation. 



PIPING FOUR HOUSES. 



I am furnishing a sketch showing four 

 liouses we wish to heat with steam. The 

 ficsired temperatures are as follows: 

 No. 1, 50 degrees; No. 2, 60 degrees; 

 NTos. .} and 4, 45 degrees, when the out- 

 side temperature is 10 degrees below 

 zero. Could the main flow pipe be run to 

 the west end of house No. 4, then across 

 tlie west end of the others and the re- 

 turns be taken direct from it? The main 

 rot urn would then run across the east 

 end of the four houses. 



If the boiler is set low enough, is it 

 necessary to have a trapf How many 

 1 '4 -inch returns are needed for each 

 house and what size should the main 

 How beT L. W. C— O. 



So far as can be determined from the 

 sketch furnished, there will be no ob- 

 .i<>ction to arranging the main flow and 

 return pipes as proposed. 



While we would prefer to have the 

 water level of the boiler four feet or 

 more below the lowest part of the coils, 

 it would answer for houses not over 300 

 feet in length if there is a difference 

 of three feet. 



A 4-inch main flow pipe will answer 

 for the four houses. It can be reduced 

 r(>spectively to 3%-inch, 3-inch and 2V1'- 

 inch after the various houses have been 

 tiiken off. For connecting the returns 

 tlie pipes should be respectively I'j- 

 iiich, 2-inch and 2'^-inch. 



For house No. 1, with a width of 

 thirtf^-five and one-half feet, we would
