The curriculum for students in Course 10-C involves basic subjects in chemistry and chemical engineering. Sludge from the reaction N a ~ C 0 3 CaO + + HzO - CaC0. Compute the velocity profile from Eq. (6.114). Mechanisms of the transport of mass, momentum and energy; similarities and differences between the three transport processes; analysis of transport phenomena in chemical engineering processes; solution methodologies for the engineering transport problems. At turbulent flow, Re is 1000 so that Assuming water at room temperature gives p = 1000 kg/m3 and p = 1 x kg/m see: Re' = 2.83 x From Figure 4-3 the f value is 56,600.

An incompressible fluid is flowing at steady state in the annular region (i.e., torus or ring between two concentric cylinders). Let us draw a second picture of the block and a second temperature profile, this time with the temperature at the hot end equal to 373.15 K. However, we will encounter here a number of physical phenomena that have no counterpart in Chapter 2. This gives in which S2 is the cross-sectional area of the nozzle opening. 474 Chapter 15 Macroscopic Balances for Nonisothermal Systems PROBLEMS 1 s ~ ~.

To apply that empiricism, D is replaced by 4R, every- where in the Reynolds and Nusselt numbers. We mention a few of these, and many more can be found in the turbulence literature. Applications such as corrosion prevention, electroplating, reactor design, batteries, and fuel cells. While the discussion applies to heat transfer coefficients based on average temperature. for the water? Assume that the pressures at the pump inlet and the annular outlet are the same.

Where does this come from? (b) Show that Fick's first law then assumes the form To verifv this vou will need the relation V,vcA + V,VC, = 0. This is done with a minimum of derivation but nonetheless no lack of vigor. All undergraduate students enrolled in Chemical Engineering courses or admitted to the Chemical Engineering program are expected to meet prerequisite and performance standards, i.e., students may not enroll in any Chemical Engineering courses or courses in another department which are required for the major prior to having satisfied prerequisite courses with a C– or better. (The program does not consider D or F grades as adequate preparation for subsequent material.) Additional details are given under the program outline, course descriptions, and admission procedures for the Jacobs School of Engineering.

In Part II, Thomson reviews convective transport, presenting a straightforward description of turbulence, and introducing the fundamental concept of transfer coefficients. The banana is placed in a convection oven that has been preheated to 400 K. SOLUTION First we equate the molar rate of evaporation of A from the liquid phase with the rate at which moles of A enter the gas phase: Here p(A' is the density of pure liquid A and MA is the molecular weight.

Here the functiong of Eq. 20.1-43 is given as and the function f vanishes. 20B.7. What is the temperature distribution, T as a function of x? 4. In addition, they serve to show how to use a variety of boundary conditions and to illustrate problem solving in Carte- sian, cylindrical, and spherical coordinates. Colloquia, special lectures and individual study in areas of current research. The velocity components can be obtained from Thus from any analytic function w(z), or its inverse z(w), we can construct a flow net with streamlines $ = constant and equipotential lines 4 = constant.
