Q:What’s the working principle of venturi ?
A: Venturi works is when the wind blows through the barrier, the barrier of the leeward side port near the surface pressure is relatively low, resulting in adsorption and lead to air flow. Venturi principle is very simple, it is to air from the coarse to fine, in order to speed up the flow rate of the gas, the gas outlet in the rear venturi tube forming a “vacuum” zone.
