Where There Is Condeosatioi 



—there is need for a Morehead Steam Trap. Condensation in 

 steam lines is akin to matter out of place — means wasted energy. 

 If your lines are sluggish — if your houses are not of uniform 

 temperature, write us. We guarantee to drain your lines per- 

 fectly — return the pure, hot condensation to your boiler without 

 pump or injector or make no charge f6r the trial. Obey that 

 impulse — write now.

 "This morning we hare 36 degrees below 

 zero, but the big Wllks Boiler kept the 

 greenhouse standing at 67 degrees from 8 

 o'clock last night until 6 o'clock this morn- 

 ing without any attention."

have no accurate way of estimating the 

 extent of radiating surface in a speci- 

 fied length or quantity of piping. In 

 other words, they have no way of esti- 

 mating what amount of piping is neces- 

 sary to supply the required radiation. 

 When they are informed that a certain 

 size of greenhouse requires a certain 

 number of square feet of radiation, 

 thejr are still in doubt as to how much 

 piping they must install. 



The following table shows the amount 

 of radiating surface, expressed in frac- 

 tions of a square foot, in each lineal 

 foot of pipe of the sizes commonly used : 



Size Pipe. Sq. Ft. Size Pipe. Sq. Ft. 



1-lnch 344 2V6-lnch 763 



1%-lnch 435 3-lnch 916 



1%-lnch 407 3%-lnch 1.047 



2-lnch 622 4-lnch 1.178 



By means of this table, it is easy, of 

 course, to compute the radiating sur- 

 face in any stated quantity of piping. 

 In 125 lineal feet of 2-inch pipe, for 

 instance, there are 125 times .622, or 

 77.75 (nearly 78) square feet of radia- 

 tion.
