Given data: Polymer flow rate: Q = 510 m/s
Mold thickness = 1.2 mm
Polymer viscosity at the process temperature = 200 Kg/m.s
Polymer density at the process temperature p = 1200 kg/m
Make assumptions about flow through the thin mold.
b. Use the cylindrical Navier-Stokes equation and cancel the appropriate terms to simplify the equation and develop the velocity equation as a function of r. C. d
