Figure 74: Geometry of an enlargement
\begin{figure}\epsfig{file=Sudden_enlargement.eps,width=11cm}\end{figure}

The geometry of an enlargement is shown in Figure 74. It is described by the following constants (to be specified in that order on the line beneath the *FLUID SECTION, TYPE=RESTRICTOR ENLARGEMENT card):

The loss coefficient for an enlargement is taken from [28].

By specifying the parameter LIQUID on the *FLUID SECTION card the loss is calculated for liquids. In the absence of this parameter, compressible losses are calculated.
