Explanation, 
For tens of feet high, remove the decimal point 
one place forward j for hundreds of feet, tv/o places , 
for thoufands of feet, three places, and fo on : and 
you will have the quantity and weight of water in 
the cylindrical pipe, fuppofing its diameter to bs 
one inch. 
The contents of cylinders of equal heights are to 
one another as the fquares of their diameters. There- 
fore, having found the quantity and weight of vva^ 
ter in a cylinder of one inch bore, you may find the 
fame for any other larger bore, by multiplying the 
above-found quantities by the fquitre of the diameter
