A nylon solid rod of diameter 5.0 mm is manufactured using a single screw extruder.

Calculate the production rate (m/min) if the operating extruder has a 7.50 cm diameter screw with a 2.25 m length, 17.7° flight angle, and a metering channel depth of 3.50 mm.

The screw is rotating at 45 rpm. The die land-length and diameter are 30.0 mm and 5.0 mm, respectively. The polymer viscosity at the operating conditions is 185 Ns/m², the melt density is 0.820 g/cm³, and the solid density is 1.12 g/cm³.
(Hint: ignore the leak flow and the die swell)
