this house. The house 15x25 feet should 

 have a l^^-inch flow or riser and four- 

 teen 1^4 -inch returns, to provide a safe 

 amount of radiation. 



HOUSE FOR VIOLETS. 



How many 2-inch pipes will be needed 

 to heat a, house 21x40 feet, to grow let- 

 tuce, radishes or violets, using hot water. 

 The house abuts on others to the north 

 and east, but the west side and south 

 end are exposed. I want to use 2-inch 

 pipe because I already have the pipe. 



J. D. 



The house 21x40 feet can bo heated 

 sufficiently for lettuce, radishes or vio- 

 lets by nine runs of 2-inch pipe, a riser 

 and three returns on the most protected 

 wall and a riser and four returns on the 

 exposed wall. That is assuming that the 

 water is maintained at 180 degrees. 



CAPAQTY OF FLOWS. 



How many returns will a 3-inch flow 

 and a 2 ^r^ -inch flow take care of, using 

 hot water? B. B. 



A 2% -inch flow pipe will supply heat 

 for 600 square feet of radiation, i. e., 

 960 lineal feet of 2-inch pipe, while a 

 3-inch pipe will supply heat for 900 

 square feet of radiation, or 1,440 lineal 

 feet of 2-inch pipe. 



TANK AND RADL«lTION. 



"Will you tell me how many runs of 

 1%-inch pipe and what size flow are 

 required to heat two connected even- 

 span houses, running east and west, one 

 to 54 degrees, the other to 58 degrees, 

 with an outside temperature of 10 de- 

 grees below zero, using hot water? The 

 houses are each 14x34 feet, 5-foot walls, 

 nine feet to ridges. The north wall 

 is boarded, the south has four feet of 

 glass, and the east end has glass gables. 

 There is a lean-to on the west 7%xl8 

 feet, 4-foot wall, 7-foot ridge, with two

Gentlemen:— You can strongly and untaesitatinrly recommend ths 

 "Eclipse" piston type reducing valve to florists. We have two purchased 

 of you last year. We would not have them out for double their cost and 

 find them as sensitive as a watch. We will be In Chlcairo soon to take up 

 the vacuum system with you. yours truly,
