INFLUENCE OF RELATIVE HUMIDITY AND MOISTURE CONTENT. 5 



The percentage yields indicated by the curves shown in the accom- 

 panying figures are based on the weight of the cleaned and scoured 

 wheat samples before the addition of the temper water. 



INFLUENCE OF RELATIVE HUMIDITY ON TOTAL YIELD OF MILL 

 PRODUCTS AND INVISIBLE LOSS. 



In figure 2 is shown the average total yield of mill products for 

 various ranges of relative humidities. Because of the influence ex-

erted on yields by the variation in the quantity of temper water 

 which differences in the original moisture content of the various 

 samples made it necessary to add in order to temper each of 15 per cent 

 moisture, the curve shown represents the combined effect of relative 

 humidity and moisture content of wheat on the total yield of mill
