Web♦ One of the basic requirements of a venturi vacuum generator is compressed air. If compressed air is not available, an electric vacuum pump is the only alternative. ♦ If constant vacuum flow is required, venturis may not be the most efficient device compared to vacuum pumps. Also, if the application requires a large vacuum flow at WebThe Venturi effect is a version of the Bernoulli’s principle, but more specifically suited to the flow of fluids through a pipe. When a fluid flowing through a pipe encounters a constriction, it means the surface area at …
