The following textbooks are available online for use in this lecture. The students can access the electronic book data via
ProQuest Ebook Central through the SIT library.

1. “Introduction to Fluid Mechanics (5th edition)”, by William S. Janna, Chapman and Hall/CRC (2015)

2. “Fluid Mechanics and Machinery” C.P. Kothandaraman , and R. Rudramoorthy, New Academic Science (2011)

The students may refer to other supplement textbooks such as: “A Physical Introduction to Fluid Mechanics” by Alexander J Smits, Wiley (1999). Most of introductory textbooks on fluid mechanics or fluid dynamics would be helpful for the students to understand the course contents. (Those who have difficulties for reading in English can refer any textbook written in their own language on hydrodynamics (such as Nagare-gaku) or fluid mechanics (such as Ryutai-rikigaku).)
