Introduction to Experimental Methods

This course covers the essential concepts and techniques used in experimental methods in fluid mechanics. It introduces key terms such as readability, least count, sensitivity, hysteresis, accuracy, precision, error, and uncertainty, and explains their importance in fluid mechanics. For example, the course illustrates how 'readability' is the ability to accurately read the scale of an instrument, using a dial gauge as an example. The course also delves into the concept of calibration, explaining its significance in obtaining precise and accurate measurements. It uses the example of a flow meter to demonstrate the calibration process, discussing the role of accuracy, precision, and error in this context. The course further explains the use of a calibration curve to correct measurements and enhance device accuracy.
