▪ I. rhe Physics.|reɪ|
[ad. Gr. ῥέ-ος stream.]
A unit of dynamic fluidity, defined variously as the reciprocal poise or the reciprocal centipoise (see quots.); also, a unit of kinematic fluidity, equal to the reciprocal centistokes.
1928Bingham & Thompson in Jrnl. Amer. Chem. Soc. L. 2879 The fluidity at 20° of a saturated solution of copper was 63·9 rhes. [Note] Reciprocal poises. 1933Physics IV. 207/2 All the alcohols have a positive association as expected, and it is appreciably higher at a fluidity of 10 rhes than at 50 rhes. Ibid. 388 (caption) Fluidity data of organic compounds in rhes at regular intervals of temperature. 1958Van Nostrand's Sci. Encycl. (ed. 3) 1417/2 Rhe, the absolute unit by which fluidity is measured or expressed. It is the reciprocal centipoise. 1961Handbk. Chem. & Physics (ed. 43) 3151 Fluidity, the reciprocal of viscosity. The cgs unit is the rhe, the reciprocal of the poise. 1974McGraw–Hill Dict. Sci. & Techn. Terms 1261/1 Rhe. 1. A unit of dynamical fluidity, equal to the dynamical fluidity of a fluid whose dynamic viscosity is 1 centipoise. 2. A unit of kinematic fluidity, equal to the kinematic fluidity of a fluid whose kinematic viscosity is 1 centistoke [sic].
