To find the temperature profile, Eq. (2.2) is used to write the flux in terms of the temperature \rr, = (q/A), = -k(dT/d.i) (2.2) Equation (2.2) can be combined with Eq. (iii): - k(dTld.x) = (Q&)(X) - C, 6% Note that Eq. (2.2) also could have been combined with Eq. (vi) in terms of the THE G E N E R A L P R O P E R T Y B A L A N C E 69 actual values of this problem. Effect of mass transfer rate on the concentration profiles. (a) Combine the result in Eq. 18.2-11 with that in Eq. 18.2-14 to get (b) Obtain the same result by integrating Eq. 18.2-1 directly, using the fact that NA, is constant. (c) Note what happens when the mass transfer rate becomes small.

Consider a Newtonian fluid and use the following dimensionless quantities: Show that the method of combination of variables gives in which q = ( A J c T ~ / ~ ~ ) ' / ~. (b) Show that the wall flux is The quantity (Re Pr D/z) = (4/m-)(wtp/kz) appears frequently; the grouping Gz = (wi',/kz) is called the Graetz number. A properly emplaced XM21 will detect significant G-agent, HD, and Lewisite munitions events and resulting clouds at ranges out to 5km with a greater than 85 percent probability of detection.

Continuation of CH_ENG 4385: application of chemical analysis and modeling to a capstone design project. The heat exchanger uses water passing through tubes (0.022-m inside and 0.025-m outside diameter). When all the unnecessary terms have been eliminated, one is frequently left with a small number of relatively simple equa- tions; and if the problem is sufficiently simple, an analytical solution can be obtained. The balance equations in their most general forms are used as the starting point for solution of common problems.

Although historically the three regions have been described as a “laminar sublayer”, “buffer zone”, and “turbulent core”, it has turned out that these are poor descriptions of the actual mechanism.* It has been discovered by detailed visual studies that the wall region is not laminar and the descriptive term “viscous sublayer” is more appropriate. What does the logarithmic profile of Eq. 5.3-4 give for the fluid velocity at the wall? There is a smooth expansion of the bed as the velocity increases above Umr, the minimum velocity for incipient fluidization.

Velocity distributions in a pipe. (Adapted from references 1 and 9.) flow, on the other hand, is blunter in shape. Use the velocity distribution to get other quantities, such as the maximum veloc- ity, average velocity, or force on solid surfaces. While the kinetic theory estimates DAA for a simple spherical molecule reasonably well, the mean-free-path method of treatment gives a very poor approximation to DAB, the diffusion coefficient of species A diffusing through a mixture of A plus B [K2, P3].
