The collision integral and Boltzmann constant are required for the Chapman- Enskog estimation of this quantity. For an ideal gas, the Sutherland equation can be used to obtain it, and the inverse of its square is proportional to the Grashof number. The stress tensor associated with it lacks a term for pressure, and it exists in dynamic and kinematic varieties. Inversely proportional to the Reynolds number, it is constant for Newtonian fluids and is almost completely eliminated in superfluids. For 10 points, name this measure of a fluid's resistance to flow.
