Taylor Number Ta</sub>)</strong> </dt>
A nondimensional number arising in problems of a rotating viscous fluid.

It may be written
NTa = f2h4/v2
where f is the coriolis parameter (or,

for a cylindrical system, twice the rate of rotation of the system); h represents the depth of the fluid; and v is the kinematic viscosity. the square root of the Taylor number is a rotating Reynolds number, and the fourth root is proportional to the ratio of the depth h to the depth of the Ekman layer. </dd>
