TABLE XXIX. 



SHOWS THE NUMBER OF IMPERIAL GALLONS THAT TANKS OF A 

 CIRCULAR, SQUARE, OR OBLONG FORM WILL CONTAIN; HAVING THEIR 

 CONTENT OR CAPACITY GIVEN IN CUBIC YARDS AND FEET, FROM 

 1 FOOT TO 500 YARDS. 



THE content or capacity of circular tanks, having the circum* 

 ference and depth given, is readily found in cubic yards and feet 

 by Table XXV.; and the content of square or oblong tanks, the 

 length, breadth, and depth being given, by Table XXVI. ; the 

 height in these Tables being reckoned the depth of the tank. 



Table XXVIII. shows the content of circular tanks, having the 

 diameter and depth given, in cubic yards and feet. 



The cubic content having been found by these Tables, or 

 otherwise, the capacity in Imperial gallons will be shown by the 

 present Table. 



In calculating the Table, fractions of half a gallon, and under, 

 are neglected ; when above half a gallon, they are reckoned 1. 



EXAMPLE. How many gallons will a circular tank contain, the 

 diameter of which is 12 J feet, and the depth 8 feet? 



In Table XXVIII., under the diameter 12J feet, 

 and opposite the depth 8 feet, stands the cubic 

 content 36 yards 10 feet; and, by the present Gallons. 

 Table, the content in gallons, opposite 36 yards, is 6058 



And opposite 10 feet, is 62 



Capacity of the tank, , . 6120 



Suppose it were wished to construct a tank to contain a certain 

 number of gallons, say about 6000, at a depth of 8 feet, what 

 would the circumference require to be? 



By this Table we find that 36 cubic yards will con- 

 tain 6058 gallons, and, on turning to Table XXV., 

 the nearest content to 36 yards, under 8 feet, is 

 found to be 35 yards 23 feet, opposite a circum- 

 ference of 39 feet; and, in this Table, opposite Gallons. 

 35 yards, stands ...... 5889 



And opposite 23 feet stands . . . . 143 



Capacity of the tank, . . 6032
