Course Description

This video is part of a series of screencast lectures in 720p HD quality, presenting content from an undergraduate-level fluid mechanics course in the Artie McFerrin Department of Chemical Engineering at Texas A&M University (College Station, TX, USA).

From Prof. Ugaz:
My inspiration for producing this series of videos has been my lifelong personal journey to understand fluid mechanics and explain its beauty to others in a straightforward way. I have received no external support for this project... the effort is purely a labor of love.

I would like to acknowledge Aashish Priye and Jamison Chang for assistance in developing the materials and preparing the captioning.

Please feel free to share any comments or suggestions.

Best wishes,
Victor Ugaz
