Theoretical equations for power dissipation and torque for single and multi‐section screw extruders for Newtonian or slightly non‐Newtonian melts are derived from improved theoretical velocity distributions. Verification of the equations is indicated by experimental data for four single‐section screws of constant channel depth. The power equations can be easily programmed on a digital computer for design or evaluation.
