Unformatted text preview: ME 467 Exam 1 Fall 2017 NAME: 9. The plot below shows extruder characteristics for two polymer extruding machines, EX1 and 4 pt EX2. Also shown are lines indicating the die characteristics for two product dies, Diel and Die2. Highest On the plot, circle the operating point that will generate the greatest (fastest) Head Pressure for a single combination of a die and an extruder. Write the combination at the right. EX1 Selected combination: Diel Extruder Melt Flow, Q EX2 Die 2 Die2 Head pressure, P 10. The plot below shows an extruder characteristic for a polymer extruding machine. Also 4 pt shown and labeled is a die characteristic for an extruded product with a circular (solid) cross- section (CS). You must now consider a square cross-section die with the same cross- sectional area as the circular cross-sectional area die. Two dashed lines are shown plotted against the circular CS die characteristic. Given the same section area for the square area die, which dashed line must be the square area die characteristic? Circle that line. Circular die section area = Ac Ac = As Square die section area = As Melt Flow, Q Square Die requires higher pressure Head pressure, p forsome CS Area sall some Q. Page 4 of 13 C...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
