...the flow of water through capillary tubes that the time of efflux of a given quantity of water was directly as the length of the tube, inversely as the...and inversely as the fourth power of the diameter. These results agree with (22a). A comparison of the formula (22o) with experiments of this kind would...

...experimentally by Poiseuille* in his researches on the flow of water through capillary tubes ; viz. that the time of efflux of a given volume of water...and inversely as the fourth power of the diameter. This last result is of great importance as furnishing a conclusive proof that there is in these experiments...

...flow of water in capillary tubes ; namely, that the time of efflux of a given quantity of water varies as the length of the tube, inversely as the difference...and inversely as the fourth power of the diameter. Let v = mean velocity of flow. d = diameter of tube. <r = weight per cubic foot of water. Then loss...
