Webapproach flow. (ii) Entrainment limit The conditions of the approach flow govern the entrainment limit and are quantified by the Froude number (see below). A critical Froude number must be exceeded for air entrainment to occur. For higher Froude numbers, the approach flow provides the driving mechanism for air entrainment. 2 WebAs the flow of oxygen passes through the constriction, a negative pressure is created. This causes the ambient air to be entrained and mixed with the oxygen flow (Fig. 6.14). The FiO 2 is dependent on the degree of air entrainment. Less entrainment ensures a higher FiO 2 is delivered. This can be achieved by using smaller entrainment apertures ...
