Prediction of a low-density binary diffusivity. Rectangular (Cartesian) coordinate; (2~~) is distance between two parallel plates Rectangular (Cartesian) coordinate Thermal diffusivity (m’ s-i, ft* s-l) Constant used in Problem 4-16 Difference, state 2 minus state 1; e.g., AT means TZ - T, Generalized diffusivity (m’ s-l, ft* s-i) Angle, curvilinear coordinate direction Viscosity (kg m-’ s-l or N m-* s, lb,,, fi-’ s-l, cP) Kinematic viscosity (momentum diffusivity) (m” s-l, ft* s-l) Ratio of circumference of a circle to its diameter (3.141592 65.. .)

Recommended preparation: ECHE 260 or permission of instructor. Tank B ( 5 m in diameter) has a depth of 3 m.3 by 0. The thermal conductivity of the material is 0.021 Btu/ft.h.0F at 320F and 0.032 Btu/ft.h.0F at 2000F. Students will use a commercial package in a design environment and will develop an understanding of the benefits and drawbacks of such tools. The velocity distribution of Eq. 10.9-15 is shown in Fig. 10.9-1.

In this state all the fluid particles in the system will be executing sinusoidal oscillations with fre- quency w, but with phase and amplitude that are functions only of position. Assume all losses due to entry, exit, and pipe fittings are already included in the lengths given. The Department of Chemical and Biological Engineering (CBE) offers undergraduate and graduate degrees in Chemical Engineering. Suppose also that gas B is noncondens- able and insoluble in liquid A, and that wAo and o,, are given.

ECE 5319 or MECE 5319, concurrent enrollment in CHEE 5120, or consent of instructor. Assume that the ground reaches 20°C by early autumn, and that the air temperature can average -20°C. J,* and U, are slightly greater than the volume velocity of 1 cm s-l, because there is a net molar and mass diffusion in the positive direction. The 30 credit hours of course credits are broken down into 5 core courses (15 cr) and 5 electives (15 cr) = 30 total credits.

The problems were chosen to introduce the beginner to a number of important physical concepts associated with the heat transfer field. Solving for V gives Using equation (3-7) together with the definition of Q[i.e., V ( nD2/4)], we obtain AP 128Qp - Vp32 --- ~ _ _ L n D4 0 2 and Note that this is a very low pressure drop, which is to be expected for air and gaseous substance at a moderate Reynolds number. Then use the boundary condition that v, = drJdt at r = rs(t) to obtain (b) Next, using the species equation of continuity in spherical coordinates with diffusion in the radial direction only, show that and indicate suitable initial and boundary conditions. (c) For short contact times, the effective diffusion zone is a relatively thin layer, so that it is convenient to introduce a variable y = r - r,(t).

The ratio N A / N B = -- of molar fluxes obtained here was first observed by Gra- ham13 in 1833 and rediscovered by ~ o o ~ s c h a ~ e n ' in 1953. Note that the units of each term in Eq. (7.45) are energy per unit time, since w appears explicitly in the potential energy term and therefore must also be included in the kinetic energy term. Applications to complex industrial problems. An introduction to the polymer technology, with emphasis on the synthesis of polymeric materials and on the polymerization processes.
