Furthermore, the term V* U can be expanded to show with the aid of Eq. (12.55): v*u=v*(vc#J)=v(v*f$)=o (12.56) Therefore, the term v(V’u) in the Navier-Stokes equation [Eq. (5.15)] is zero. There are a number of equations available for estimating the diffusion coefficient of gases [Pl, Rl]. Massachusetts Institute of Technology (1948). Theory and practice of basic separation methods, reaction engineering, process controls, and other fundamental chemical engineering disciplines as well as regulatory requirements to prevent unnecessary waste generation.

Ultrasonic flow meters are highly recommended for those applications that require no internally mounted components in the flow. Automatic ideal reactor models with generation of kinetic expressions based on chemical formulas. A more complete review of timedependent behavior is to be found elsewhere [B7, M4]. 15.1.3 Viscoelastic Behavior Some non-Newtonian fluids exhibit both fluid-like (viscous) behavior and solid-like (elastic) behavior; these are termed viscoelastic.

Of course, we want Eq. 1.2-5 to simplify to Eq. 1.1-2 for the flow situation in Fig. 1.1-1. A truly sharp-edged orifice plate is machined with a complete bevel on the downstream side so that entering flow first encounters a knife edge. This specialization provides the necessary preparation for students wanting to do graduate work in biomedical engineering or work in a career with an emphasis of medical applications of chemical engineering.

The molar average velocity appears in the equation for the total molar flux, NT/A (units kmol m-* s-i), which comes from applying Eq. (3.21) for the case of total moles being convected: (NT/A), = cTuf, (5.23) where Uz is the z component of the molar average velocity U*. An analysis of the Bernoulli Equation (inlet, 1, is liquid surface in the tank; outlet, 2, is the exit) be known in order to find C. and V2 are known. because equation (2-37) requires that a value for V. considerably different for Venturi and orifice meters (see Figures 2-23 and 2-24). the equation is (2-34) Likewise.

The Reynolds analogy assumes that the turbulent diffusivities are all equal and that the molecular diffusivities of momentum (μ/ρ) and mass (DAB) are negligible compared to the turbulent diffusivities. This well-known result provides the limiting value of Nu for heat transfer from spheres at low Reynolds and Grashof numbers (see s14.4). (d) In what respect are the Biot number and the Nusselt number different? 10B.2. However, of more interest is that in many industrial catalysts the diffusion mechanism is governed by both Knudsen and molecular (Fickian) diffusion (i.e., the transition region [R3, Wl]).
