Input (English): method to measure this property uses spring plates which are vibrated at uniform amplitude and frequency. The energy input is then measured. The classical method to measure this quantity uses a capillary tube, and is named after (*) Stokes. This quantity is almost independent of pressure and density in gases, but increases with temperature; in liquids, however, it decreases as temperature increases. This quantity can be calculated using Newton's equation describing fluid motion, and its kinematic version is equal to the dynamic version divided by the density. It is given by the ratio of shear stress to the velocity gradient. For 10 points, name this property of a fluid measured in units of poise, the resistance of a fluid to flow.
Output (English): Science
