Melt Pressure - an overview ScienceDirect Topics

If the melt temperature is the same and the shear rates are similar, the melt viscosity in the different channels will be the same. This leaves the pressure drop to balance the resistance in each section or leg of the die. The pressure drop is calculated from Eqn (49.2): (49.2) Δ P = 2 × τ × l h. where.
