The Kolmogorov length, velocity and time are $\eta=(\nu^3/\epsilon)^{1/4}$, $v_\eta=(\nu\epsilon)^{1/4}$ and $\tau_\eta=(\nu/\epsilon)^{1/2}$. With $\epsilon\sim u^3/\ell$, their ratios to the <integral scales of turbulence> are powers of the <Reynolds number>. They describe a mean scale balance; intermittent dissipative structures can have other local scales.
