the machine, and above this speed, the capacity varies in- versely with the speed. The transition at which this occurs is defined (Rose and English, 1967) as the critical speed (NF), and it is obvious that the maximum capacity of a machine w~ll be at the critical speed. At the critical speed (Nc,, DT/[G-(S+T)] = 450 g/N2, (7) Eqs.
