One quantity named for this scientist, whose namesake averaging is used to simplify the Navier-Stokes equation, is equal to velocity times linear dimension over kinematic viscosity and gives the ratio of inertial forces to viscous forces. For 10 points, name this British scientist who names a quantity that's high for turbulent flow and low for laminar flow.
