We provide you with a detailed Year-wise, semester-wise, and Subject-wise syllabus in the following link B.Tech Plastics Technology Syllabus Regulation 2021 Anna University.
Aim of Concept:
To enable the students to understand the basic concepts of rheology
- To analyze the flow behavior of polymer melts
- To understand the basics of fluid mechanism and to analyze behavior of Newtonian fluids.
- To familiarize with instruments such as orifice meter, Venturi meter and Pitot tube.
