Determine the correctness or otherwise of the following Assertion [a] and Reason [r]: [a]: Nylon 6 should be thoroughly dried before melt spinning [r]: The gl...

In melt spinning of a monofilament, a polymer is being extruded at a volumetric flow rate of 5 × 10⁻⁵ m³/s through a spinneret of circular cross-section. If the...

In melt spinning, the diameter of monofilament at the spinneret exit is 0.3 mm and at the take-up point is 0.15 mm. Assuming that there is no change in density...
