The results of investigations relative to formulas for the flow of water in pipes (1890)
Weston, Edmund B[rownell], 1850- [from old catalog] · [New York] · leaf 54
e conditions upon which the co-efficient of friction£ was dependent, and after considerable preliminary platting, computa-tion and study, it was found to be dependent, in this instance, upon boththe diameter and the square root of the velocity. The process by which the formula was finally… … An independent formula £ = a -j- /i */v was first determined for each diameter of pipe that the experimental data embraced. The numerical values of a and /? were deduced graphically in thefollowing manner by the aid of the expression C +/v, which is the equa-tion of the straight line o Jc, Fig. 1…
