β¦ Synopsis
It being known that H 'p ~ It p ~ t[, there must be an inversely proportional relation between values in which these values H f', H t and/-/take the place as divisors. Hence, and in consequence D" > D p > D. This result may be expressed in words as follows : II. The diameters of the pipes, at any level of the supply-pipe line, may (in order to permit the body of water to deseend at uniform rate through the entire length of the pipe, or to descend in unimpeded adaptation of its shape to the laws of gravitation) be decreased at the rate of the fourth root of the head above such level increases, the required diameter being in all cases as D = d" 4-V'7~
