Calculate this factor as a function of temperature. The fundamental aspects of plasticity in engineering materials, strengthening mechanisms, and mechanical failure modes of materials systems. We postulate that v, = 0, v, = 0, v, = vr(r, O), and 9 = 9(r, 8). (a) Show that the equation of continuity in cylindrical co- ordinates gives v, = f (O)/r, where f(8) is a function of 8 for which df/d@ = 0 at 0 = 0, and f = 0 at 8 = ~ / 2. (b) Write the r- and 8-components of the creeping flow equation of motion, and insert the expression for f(0) from (a). (c) Differentiate the r-component of the equation of mo- tion with respect to 6 and the 8-component with respect to r.

Straight lines through Lb, v and L,, V, respectively give b point P. This type of scale-up, also called equal Froude number, is less commonly encountered. 5. From this, the diffusion coefficient can be calculated. The density and concentration are related by PA = CAMA (2.33) When Eqs. (2.31) and (2.33) are substituted into Fick’s law, the result is O'AIA)~ = -D(dpAldx) I (T = constant) (p = constant) (2.34) where the diffusion coefficient D in Eq. (2.34) is identical to thz& in the previous equations.

An interesting extension of this problem is consideration of the heating effects in the viswmeter.

In nature many processes are analogous in that they can be described by similar physical models, common mathematics, and other aspects. This class of problem is known collectively as “creeping” flows. Feed rate is 3.0802 0. what is the reflux ratio? 12-27. You’ll study topics such as: advanced reactor design; chemical reaction mechanisms and rate theories, transport effects in reactive systems, and rate expressions for complex and heterogeneous catalytic reaction system.
