SIZE OF STEAM LINE. 



What size steam line will it take to 

 supply three houses each 18x200 for 

 carnations and one house 21x200 for 

 roses and what size opening will it take 

 in the boiler to supply the size line that 

 is required? The houses are five feet 

 to the gutter and ten feet to the ridge.

pipe running under the ridge to the far 

 end of the house and returning by nine 

 2-inch pipes in each if they are detached 

 and separated by alleys. If separated 

 only by division walls use nine returns 

 in each of the outside houses and eight 

 in each of the protected houses. If the 

 houses are built on the ridge and fur- 

 row plan and the space under the roof 

 forms a single room, the last plan should 

 be followed. L. C. C. 



To supply the four houses in question 

 with steam the main supply pipe should 

 be a 6-inch. If the boilers are provided 

 with 4-inch openings and are worked in 

 a battery of two or three, better satis- 

 faction will be secured than from using 

 one large boiler. The boilers can be 

 yoked together by a cross line of 6-inch 

 pipe fed from the boilers through 4-inch 

 ripples. L. C. C. 



PIPING FOUR HOUSES. 



I am building four houses 15x112, 

 running east and west, glass in the west 

 end, south wall three feet high, with two 

 feet of glass. I have two No. 1 Kroe- 

 schell boilers rated to heat 6,000 feet of 

 glass each, also some 2-inch pipe. How 

 shall I pipe the houses to maintain a 

 temperature of 60 degrees in 15 below 

 zero weather! F. E. K. 



As it is not stated, I assume that the 

 lour houses are separated by division 

 walls. If 80, the following amount of 

 piping will be required. One 3-inch flow 



TOO FAR AWAY. 



I have a greenhouse 18x100, the hot- 

 water heating plant being located at 

 one end. T wish to add another house 

 9x32 at the farther end. This house 

 will have a double boarded wall four 

 and one-half feet high on the north side, 

 the south side two and one-half feet 

 boarded and eighteen inches glass. The 

 west end will be glass above two and 

 one-half feet. The sashbars are seven 

 feet on one side and six feet on the 

 other, the ridge being seven feet high. 

 The flow pipes are 2^ -inch and the re- 

 turns 2-inch, Under the center bench 

 I wish to run a 1%-inch pipe for the 

 flow for the new house, or would you 

 run 2-inch? What size pipe for returns 

 will be needed and how many to keep 

 the small house at 40 degrees in zero 

 weather? e. L. 



through the house will be adequate. If 

 the boiler is at one end of the house 

 18x100 feet and the new building is at 

 the opposite end, there may be some 

 difiiculty in heating this house during 

 severe weather, but under ordinary con- 

 ditions it should not be diflBcult. The 

 chief obstacle to success in heating this 

 house will be found in the length of the 

 flow pipes, if they are as I have assumed 

 in the above statement. L. C. C. 



The amount of piping necessary for 

 your house 9x32 should be as follows: 

 A riser or flow of iy2-inch pipe will be 

 ample to supply heat for the house pro- 

 vided the water is at a temperature of 

 170 to 180 degrees. With water at this 

 temperature nine 1^4 -inch returns 



FLOWS AND RETURNS. 



The main house is 17x80 feet and nine 

 and one-half feet to the ridge, with 

 three benches; bottom heat. I have 

 figured on three lines of 2-inch flow pipes 

 the length of the house, with twelve 

 lines of 1^-inch return pipes. Also two 

 lines of 2-inch and six lines of 1^4 -inch 

 to heat a small house which is connected 

 to the larger one. The small house is 

 10x80. My heater is a Wilks 30x42. 

 Will one 2-inch flow and one 2-inch re- 

 turn be enough for all the water pipes, 

 or shall I use two of eaoh? The heater 

 has two 3-inch openings at top and bot- 

 tom. I will want a temperature of 60 

 or 65 degrees with zero weather.

The house 17x80 feet requires 550 feet 

 of radiation. This can be supplied by 

 the use of one 2i/^-inch flow pipe and 

 fifteen 1^4 -inch returns, five under each 

 of the three benches. The small house 

 requires 340 feet of radiation, which can 

 be cared for by using a 2-inch flow from 

 the boiler to the distant end of the house 

 and nine 1^-inch returns. If your heat- 

 ing plant is so arranged as to permit
