Measurement System

This course covers the essential concepts of units, dimensions, and measurements in fluid mechanics. It begins with an understanding of static and dynamic measurements, the systems of units and dimensions, and the significance of primary dimensions. For example, the course explains how the diameter of a tube, a length dimension, can be measured in centimeters or inches. It further discusses the International System (SI) of units and the challenges faced when using mass and force as primary dimensions. The course also delves into the three stages of a measurement system: the detector transducer stage, the intermediate stage, and the output stage. It concludes with an introduction to system response, distortion, and impedance matching, using the example of a transducer to illustrate these concepts.
