One form of this quantity over the rate of thermal diffusivity is the Prandtl number, and Sutherland's formula calculates this quantity for an ideal gas as a function of temperature.
One form of this quantity over the rate of thermal diffusivity is the Prandtl number, and Sutherland's formula calculates this quantity for an ideal gas as a function of temperature. The Navier-Stokes equations reduce to the Euler equations when heat conduction and this quantity are zero. It is independent of stress for Newtonian fluids, and the ratio of the inertial forces to the forces caused by this property is known as the Reynolds number. This quantity's kinematic form is found by dividing its dynamic form by the substance's density. This quantity, which is zero in superfluids, contributes to turbulence when decreased. For 10 points, name this quantity, a fluid's resistance to flow.
