Vocabulary : Turbine to Turbot
Turbine : A form of steam engine analogous in construction and action to the water turbine. There are practically only two distinct kinds, and they are typified in the de Laval and the Parsons and Curtis turbines. The de Laval turbine is an impulse turbine, in which steam impinges upon revolving blades from a flared nozzle. The flare of the nozzle causes expansion of the steam, and hence changes its pressure energy into kinetic energy. An enormous velocity (30,000 revolutions per minute in the 5 H. P. size) is requisite for high efficiency, and the machine has therefore to be geared down to be of practical use. Some recent development of this type include turbines formed of several de Laval elements compounded as in the ordinary expansion engine. The Parsons turbine is an impulse-and-reaction turbine, usually of the axial type. The steam is constrained to pass successively through alternate rows of fixed and moving blades, being expanded down to a condenser pressure of about 1 lb. per square inch absolute. The Curtis tTurbinella : A genus of large marine gastropods having a thick heavy shell with conspicuous folds on the columella.
Turbinite : A petrified shell resembling the genus Turbo.
Turbinoid : Like or pertaining to Turbo or the family Turbinidae.
Turbit : The turbot. ;; A variety of the domestic pigeon, remarkable for its short beak.
