5. Galley Vent System
__________________
A. The galley is ventilated by a system consisting of flexible ducts which connect an inlet vent at the galley ceiling to an exhaust nozzle in the airplane skin. The nozzle incorporates a flow limit-venturi. An acoustic muffler is incorporated in the ducts to reduce noise from the system. The muffler is attached to the ducts and to structure by clamps (Fig. 3).
