Abstract: | A criterial equation for determining the energy dissipation in the channel of an extruder screw is obtained analytically for a Newtonian model of the extrudate. It is shown that for actual extruders the dissipation does not depend on the pressure in the die.Moscow Region. Translated from Mekhanika Polimerov, No. 5, pp. 924–927, September–October, 1969. |
