Abstract
It is the aim of this paper to examine experimentally the fitness of Bagley's method for the end correction of capillaries. The experiments were performed with the silicone fluid of 6×103 degree of polymerization as materials by using capillaries and reservoirs of various dimensions.
Even in case the linearity of P-l</r relation of a given capillary, at constant shear rate, (P as applied pressure, l as capillary length, and r as capillary radius) is perfect, should capillary radius be varied, the end corrections will cease to agree between them.
The above disagreement is well illustrated by introducing the effect of pressure loss resulting fromflow through the reservoir into the total pressure loss.
