Introduction to Fluid Mechanical Engineering: From a Straw to an Airplane

Department: Engineering


Instructors: Reema Hajjar and Jeffrey Mankey
Instructors' Email:;
Prerequisites: None

Course Description

This course introduces students to the world of engineering, in particular aspects involving fluid mechanics. Water covers around 70% of the Earth's surface, and we are surrounded by air every day. Good understanding of their properties allows engineers to manipulate these fluids to improve our lives, from drinking water through a straw to traveling up high in the air. Students will learn the fundamentals of fluid mechanics behind different engineering applications, and be able to explain interesting fluid phenomena in daily lives. They will apply creativity, scientific knowledge and hands-on experiments to solve different engineering problems. Students will also be exposed to state-of-the-art research in fluid mechanics to broaden their outlook and inspire motivated students to pursue a research career.
