Unformatted text preview: molecular weight increases from 40,000 g/mol to 80,000 g/mol? 5. Production of a nylon fiber requires spinning the fiber at a speed of 200 m/minute. If fiber is extruded through a hole 1 mm in diameter and the length of the hole is 5 cm, what is the pressure drop required across that hole? The viscosity for nylon under the processing conditions is 1400 poise. 6. For each of the items below, choose the processing technique that would be used to make the item. a. tray for frozen food b. plastic measuring cup c. thread for sewing d. a turkey made from epoxy (Thanksgiving decoration) e. drinking straw...
