WebThe Venturi effect describes how the velocity of a fluid increases as the cross section of the container it flows in decreases (like when flowing through a funnel). The energy in this increased speed comes by reducing the static pressure of the fluid. In the case of tidal stream generators, a duct or shroud (otherwise known as a diffuser) can be used to … WebJun 15, 2004 · For the required oxygen concentration to be delivered to the patient, the flow rate from the venturi must exceed tidal flow. In normal adults, tidal flow peaks at about 30 l.min −1. A normal flow pattern is shown in Fig. 2 with a hypothetical venturi flow rate shown at 32 l.min −1. In this case the excess oxygen mixture blows out through ...
