| Popis: | A capillary tube viscometer is described that dispenses with direct pressure measurements by comparing capillary tube flow rates of a fluid whose viscous properties are unknown and a standard Newtonian fluid. Since only flow rate measurements are needed, the experimental technique involves only time and mass measurements and knowledge of the geometry of the capillary tubes. Using this instrument, the viscous properties were measured for distilled water and glycerol as examples of Newtonian fluids and for several polymer solutions as examples of power-law fluids. For distilled water, the measured viscosity agreed with the best value available in the literature within 0.55%. |
