Weber numbern.

Brit.

/ˈveɪbə ˌnʌmbə/, U.S.

/ˈveɪbər ˌnəmbər/

Forms:

α. 1900s– Weber's number.

β. 1900s– Weber number.

Origin: From a proper name, combined with an English element; modelled on a German lexical item. Etymons: proper name Weber , number n.

Etymology: In α. forms < the genitive of the name of Moritz Weber (1871–1951), German naval engineer, who first defined the ratio in 1919 + number n., after German webersche Zahl (F. Eisner 1932, in Wien & Harms Handb. d. Experimentalphysik IV. iv. 225). In β. forms < the name of Moritz Weber + number n.

Physics.

The ratio between the inertial forces acting upon a fluid flowing through a fluid medium and its surface tension, frequently used in the study of the formation of bubbles and droplets; (occasionally also) the square root of this ratio.The Weber number is frequently expressed as ^ρlv²/ _γ, where γ is the surface tension of the fluid, ρ its density, l the characteristic length, and v the velocity of the fluid.

1937 M. P. O'Brien & G. H. Hickox Appl. Fluid Mech. v. 149 The first three terms [in the coefficient of discharge] merely represent the geometrical similarity including the roughness. The other two are Weber's number and Reynolds' number.
