AMOUNT OF SEWAGE PER CAPITA 141 



44. If 75 gallons per head per day in New York City are wasted, 

 and can be eliminated, what would be the ratio of the maximum daily 

 rate to the average, after the waste is stopped? What is it now, by 

 Fig. 27? 



45. From Fig. 33 determine the average and maximum rates, if they 

 are corrected on the assumption that the night flow is hiefly waste and 

 can be reduced to 1000 gallons per hour. What percentage then will the 

 maximum be of the average? 



46. The average daily water-consumption of a city is found to be 

 5,000,000 gallons. What rate of flow, in cubic feet per second, should 

 be taken for the sewage flow? Use Baumeister's rule, and then compare 

 with the suggestions of p. 138 and p. 139.
