Input (English): Time independent forms of this quantity can be modeled as a power law with the Ostwald-de Waele equation, where n greater than one means the material is dilatant. This quantity is large when convective acceleration can be neglected, allowing Stokes's law to be applied to a spherical object. For a dilute gas, this quantity is proportional to the square root of temperature in a theory named for Chapman and Enskog. This quantity can be measured with a Zahn cup in one industry, and in units of Saybolt Universal Seconds in the petroleum industry. Its (*) kinematic form is equal to its dynamic form divided by its density. Body armor has a unique shear thickening form of this quantity, because in non-Newtonian materials this quantity changes with applied stress. Stokes law gives the drag associated with this quantity. For 10 points, name this property of a fluid that describes resistance to flow.
