The Prandtl number is the
The Prandtl number is the ratio of this quantity to thermal diffusivity. Euler's equation is used if this quantity is assumed to be negligible, and it can be measured in either stokes or poise. The Reynolds number is equal to the ratio of inertial forces to forces attributable to it. The kinetic type is equal to the dynamic type divided by the density, and this quantity is constant in Newtonian fluids. For 10 points, give this term for a fluid's resistance to flow.
