Displacement and Area Measurement

This course covers the principles and applications of displacement and area measurement in fluid mechanics. It starts with an in-depth discussion on impedance matching, which is crucial for understanding the impact of the measuring system on the physical variable being measured. The course then explores the concept of displacement and area measurement, using pneumatic displacement gauges and gauge blocks as illustrative examples. It underscores the importance of regular calibration of measuring instruments to prevent errors caused by mechanical wear and deformation. The course wraps up with a detailed explanation of how to measure small distances using a pneumatic displacement gauge, treating air as an incompressible fluid. Additionally, the course delves into experimental methods in fluid mechanics, focusing on the sensitivity of pneumatic displacement gauges and the use of the polar planimeter for area integration.
