George Batchelor names a value of this quantity that characterizes the impact of molecular diffusion. The “integral” version of this quantity is defined by a spatial integral of the autocorrelation function and is generally larger than a related (15[1])quantity (-5[1])named (15[1])for Taylor. One characteristic value of this quantity is defined as nu cubed over epsilon, all raised to the one-fourth power, where nu is the kinematic viscosity and epsilon is the rate of (*) dissipation. (10[1])Kinetic energy cascades (15[1]10[1])from (15[1]-5[1])eddies with high values of this quantity to eddies with low values (10[1])of this quantity according (10[1])to (-5[1])Kolmogorov's theory (10[2])of (10[1])turbulence. (10[1])Density times flow velocity times this quantity is the numerator of the Reynolds number. For 10 points, the period of a simple pendulum is (10[2])proportional (10[1])to the square root (-5[1])of (10[1]0[1])what quantity? ■END■ (10[2]0[2])
