#venturi effect

Introduction The Venturi effect is a principle in fluid dynamics that describes how fluid speed and pressure change as it flows through a pipe with varying cross-sectional areas. This phenomenon is named after Giovanni Battista Venturi, an Italian physicist. Fundamental Principle The Venturi effect is a direct consequence of the principle of conservation of energy applied to fluid flow,…

I'm not massively knowledgeable on the physics of pneumatics, but I thought I'd share a rather interesting effect that I come across quite often as a means to safely regulate airflow in industrial equipment.

Enter Giovanni Battista Venturi.

He was an Italian physicist and diplomat who studied fluid mechanics (of which the effect still applies). The effect works so well in the industrial pneumatics equipment I've come across because it allows blockages to occur while still leaving the main compressors to have free airflow and not burning out the motor and also providing suction to other areas of the machine. Although (in some cases) not as efficient, it does allow mechanically simple control of airflow with fail safes.

If one of the spurs of a piece of equipment gets blocked the pressure remains relatively consistent throughout the run. It's a simple principle often overlooked in industrial applications. From fuel injectors to wind instruments, it amazes me the relative simplicity and reliability of the Venturi effect and its many applications.

DIY Paint Booth Exhaust Using the Venturi Effect – Part 2

The paint booth that I converted from an old TV cabinet is complete. I left off with adding and exhaust vent at the top of the cabinet. The next step is to ventilate the cabinet and put in a paint booth exhaust of some kind. I did a bit of research. There were plenty of options available. Box fans, computer fans and squirrel cage fans were just a few of the options I ran into.

I had…
