Assume that the tempera- ture dependence of viscosity may be expressed by an equation of the form p = AeBIT, with A and B being empirical constants; this is suggested by the Eyring theory given in 51.5. In the defining equation for Reynolds number [Eq. (6.1)], the characteristic velocity is the tip speed, Eq. (9.7). Contributions from such forces as the centripetal and Coriolis forces are the source of. the additional terms that appear in the momentum balance equation in curvilinear coordinates.

After some time diffusion oc- curs and the parabola begins to get fuzzy, of course. The absence of vapor does not preclude the presence of contamination. Because of the need for fluid flow measurement, much effort has gone into the development and design of fluid meters.

Table 14.1 summarizes the results at all temperatures. Pressure-volume-temperature relations; chemical equilibria by Gibbs' method; vapor-liquid equilibria; thermodynamic calculations by third law and quantum-statistical methods; irreversible thermodynamics and information theory. This relaxation of stresses after the fluid motion has stopped is characteristic of viscoelastic materials. (c) What is the normal stress 7,, during steady shear flow and after cessation of the flow? Note that the scalar product of a vector with itself is just the square of the magnitude of the vector The rules governing scalar products are as follows: Commutative: Not Associative: Distributive: The length of this vector equals w ,4, Area (v. w) (A.1-7) (A. 1-8) (A. 1-9) (A.1-10) Fig.
