mean rate of energy loss through viscous dissipation is balanced by their mean
rate of gain through the Kolmogorov energy cascade
(Chapter 6)
. If the rate of
viscous dissipation were larger than the cascade rate, the kinetic energy of the
dissipative eddies would decrease, decreasing the dissipation rate - and vice versa.
