It is assumed that the ejector cost can be expressed in terms of
the primary area, A , and the throat area, Al.
4.4.2 THE EJECTOR AREA
Mixing Section
The ejector surface area is calculated from the following geometric
relationships.

LM = 7.8 D

Large R = Small R + LM TAN 2.50

A. Area = n(Large R + Small R)/(LM) + (Large R - Small R)
