A Venturi chamber, or carburetor, is a common component of bongs and water pipes used for smoking cannabis.
It creates airflow patterns that can improve efficiency and smoothen inhaled smoke.
What is a Venturi Chamber?
A Venturi chamber refers to the narrow constriction along the air passage of a bong or water pipe with slits or holes on the sides.
This section is located below the bowl and downstream of the water filtration system.
The Venturi effect causes the smoke to speed up and create a lower pressure area when passing through the narrowed chamber.
This draws in additional air through the slits or holes, diluting and cooling the smoke before it reaches the user.
The rushing air also creates a “chugging” sound as smoke bubbles up through the water chamber. Venturi carbs optimize this by enabling further air mixing just before inhalation.
The intake of fresh air can make hits smoother and easier on the lungs. It also helps stack or collect smoke within the chamber so users can inhale large amounts.
Some designs allow users to cover or uncover the carb to control airflow and hit strength.
Overall, Venturi chambers provide added functionality and percolation for bongs, allowing optimal inhalation.
They demonstrate applications of fluid dynamics principles in one of the most common marijuana consumption tools.
