THE STEAM NOZZLE.

exhaust space. The pressure at the nozzle mouth was
about atmospheric.
In general it may be said that if the pressure of a steam
jet issuing from a nozzle be greater than that in the region
into which it is discharging, lateral expansion of the jet
takes place immediately beyond the nozzle, and pressure
oscillations are set up in said region of lower pressure.
Such oscillations become a minimum or vanish if the pres-
sure of the jet leaving the nozzle is the same as the exhaust
pressure, or pressure in the exhaust space, whilst if the
latter pressure is higher than that which the jet would have
after full expansion in the nozzle, the pressure rises in the
nozzle at a distance from the mouth depending upon the
amount of the exhaust pressure.
