In addition to learning general measurement methods and the application of Bernoulli's theorem, the experiment involves comparing pressure losses in a Venturi tube and an orifice plate, as well as determining the pressure loss in a sudden expansion pipe. The Pitot tube system within the device also derives the velocity distribution and flow coefficient in the transparent pipe cross-section direction.

This open-type suction wind tunnel allows for a wide range of experiments related to fluid dynamics, despite its compact design. It consists of a large bell mouth with a honeycomb, a two-dimensional converging nozzle, an experimental area (125x125mm), a diffusion section, a protective mesh, a variable-speed fan, and a silencer unit, achieving a flow with minimal turbulence.

Smoke wind tunnel experimental device
This is a specially designed small wind tunnel to visualize the airflow around a model. The compact device can be demonstrated in various locations, such as classrooms, regardless of the laboratory setting, and can be easily moved and stored when not in use.
