Experimental validation of pressure loss in anemometer testing equipment

This work deals with an experimental procedure to validate theoretical equations used for pressure losses inside anemometer testing equipment. This equipment allows for the generation of air flow inside a chamber designed for anemometer calibration testing at different air speeds. To calibrate anemometers to high accuracy, the air flow must have very low turbulence and uniform velocities over the testing chamber cross section. For high performance, the anemometer testing equipment used a closed-circuit wind tunnel design.
