VENTILATION TABLES. 



In order to ventilate a bam proper- 

 ly there must be a certain amount of 

 air space for each head of stock ac- 

 commodated, for no system of ventila- 

 tion could be devised which - would 

 work successfully in a bam where 

 there was only 200 or 300 cubic foot 

 of air space for a cow. It has "been 

 found in actual practice that every 

 cow should have at least 600 cubic 

 feet. Horses require more and smaller 

 stock less. 



Air space for stock in a stable: 

 Horses, 8O0 to 1000 cubic feet each; 

 cows, 600 to 800 cubic feet each; hogs, 

 300 cubic feet each; shee<p, 200 cttblc 

 feet each. 



Now this 800 cu^bic feet of air space 

 for each cow has to be changed con- 

 stantly; that is you will understand 

 every hour this 800 cubic feet has to 

 be changed four or five times. 



Cows must have 4,000 cuhlc feet per 

 cow per day; horses, 5,000; pigs, 1,S00; 

 sheep, 1,000. 



With these requirements in mind It 

 has been found that for every cow In 

 the stahle there must be at least 8 

 square inches of inlet area. Of course, 

 instead of making an aperture in the 

 wall for each cow, it is customary to 

 put in one big ventilator which will 

 admit sufficient air for half a dozen. 

 The total inlet of the galvanized ven- 

 tilator mentioned is 48 square inches, 

 and it is intended for 6 cows. 

 1 galvanized ventUator for 6 horses; 

 1 galvanized ventilator for 6 cows; 

 1 galvanized ventilator for 12 hogs; 

 1 galvanized ventilator for 16 sheep. 



The same ideas govern the size of 

 the outlets. Tlieoretically the total 

 area of the outlets should be equal to 

 that of the inlets. In practice it is 

 customary to provide almost twice as 

 much outlet area as inlet, for air comes 

 through windows and doors, and 

 cracks sometimes, during part of the 

 day. A safe figure to go by is 15 

 square inches of outlet area for every 

 cow. It is not thoueht advisable to 

 have an outlet less than 18 inches in 

 diameter. 16x16 is the minimum. 

 Make them 18x18 if you can. and if 

 this is too large control vnth a dam- 

 per. You can figure on having one 

 outlet 18x18 for every 20 cows in the 

 staWe.
