THE STEAM INJECTOR.
The delivery nozzle of an injector is of the greatest im-
portance, as the diameter of its throat or portion of
smallest cross-sectional area is the size by which the
capacity of the injector is determined and with which the
other dimensions of the injector are compared. The quan-
tity of water delivered by two injectors under similar con-
ditions varies with the square of the diameter of the throat
of the delivery nozzle.
The area of the delivery nozzle throat to pass any par-
ticular quantity of water in a given time depends upon tlie
