Engineering Metrology deals with the semester V subject of Anna University B.E Production Engineering syllabus. In this article, we try to provide the unit-wise syllabus for academic purposes in one place.
We started to analyze the situation of students who are often confused about the syllabus. What are the topics do they include in the syllabus? In this article, you can simply find the detailed syllabus of the semester V PR3501 – Engineering Metrology. I hope this information is useful. We also provide the required books and references regarding the subject especially.
If you want to know more about the syllabus of B.E. Production Engineering and Management connected to an affiliated institution’s four-year undergraduate degree program. We provide you with a detailed Year-wise, semester-wise, and Subject-wise syllabus in the following link B.E. Production Engineering and Management Syllabus Regulation 2021 Anna University.
