This course is structured as a MOOCS course for students or junior engineers studying chemical, mechanical or civil engineering. In this course, effort will be made to introduce students /engineers to fluid mechanics by making explanations easy to understand, including recent information and comparing the theories with actual phenomena. The following features will be included in the course1. Many illustrations, photographs and items of interest will be presented for easy understanding. 2. Assignments and exercises will be given at the ends of course lecture to test understanding of the chapter topic. 5. Special emphasis will be given on real multiphase flow phenomena with specific applicationsINTENDED AUDIENCE: Chemical Engineering, Civil Engineering and Mechanical Engineering UG and PG students and FacultyPREREQUISITES: Nil.INDUSTRY SUPPORT: Chemical Industries, Flow reactor handling, Piping system, Metering fluent etc.
