The principal purpose of this book is to provide readers with a variety of measurement techniques frequently used in fluid mechanics and heat transfer experiments. Many books introducing the principles of each technique are available. However, an easy-to-use book combining the basics, test setups,calibration procedure and results, and examples has yet to be introduced. The authors hope that, with the introduction of this book, the readers can quickly learn both the overall and detailed aspects of each experimental technique and then apply these to their own work.
