Question 15
XE-FNAT2 marksNeeds review
A single screw extruder is operating at a rotational speed of 2 revolutions per second for the extrusion of a Newtonian polymer under open-discharge conditions (in absence of a die, the pressure drop,
= 0). The extruder has a screw diameter,
= 5 cm, a channel depth,
= 0.4 cm, distance between flights,
= 1 cm, and a helix angle,
= 20°. Assume the value of
= 3.14. The volumetric flow rate (rounded off to 2 decimal places) is ______ cm³/s.Log in to check the answer
