C.l-9): Show that the boundary conditions are O = 0 for 77 = co and O = 1 at 7 = 0. (el In Eq. 12B.4-7, set dO/dq = p and obtain an equation for p(rl). Turbines are usually gas- or steam-powered and are typically used to drive pumps, compressors, blowers, and other refinery process equipment. These agents generally have a lower vapor pressure and a dramatic increase in inhalation toxicity. In practice the scale on a well manometer, instead of being a true meter stick as used in the U-tube and inverted manometers, is a scale calibrated to correct for (AZ),, and to read AZ directly.

Equations (12.2) need not be used to obtain the solution for U, and U,. Equation (5.61) -rated for constant area and diffusion coefficient by separation ofvariables. Design and modelling of electrochemical cells. The specific volume of water is 0.0161 ft3 lb,‘, and the density is the reciprocal: 62.11 lb,,, ft-‘. Flow around objects is a somewhat more complicated situation than flow in conduits. To use dimensionless groupings, we rewrite Eq. 5.3-2 as in which A is a constant simply related to A'; the kinematic viscosity v was included in order to construct the dimensionless argument of the logarithm.

A water-based solvent (2 percent acetone) has an exit acetone concentration of 15 percent. What are the dimensions of these quantities? The convection term in Eq. (7.2) can be modified by using the definition of the dot product (U * ds): “ZdV = -f (lpU)(cos I s - e) dS - f (Yv, * ds) S ‘I +&.~w+J--&dV s where the angle 8 is between the velocity vector U and the normal vector N (perpendicular to the area through which the transfer is occurring). Consider tubes with various roughness (see Figure 3-2).

Laminar Flow along SOLUTION a Flat Plate (Exact ~olution)' This problem may be solved by using the definition of the stream function in Table 4.2-1. Automatic or manual shutoff systems at supply headers are needed for top and bottom loading in the event of leaks or overfills. Note also that this derivation eliminates C, from the final equation. Turbulent flow introduces no new transport mechanisms. The American Chemical Society was founded in 1876 and, in 1908, it organized a Division of Industrial Chemists and Chemical Engineers while authorizing the publication of the Journal of Industrial and Engineering Chemistry.

Develop an expression for the total pressure in each reservoir as a function of time, assuming that the flow of each gas through the connecting duct follows Eq. 24.6-1, and that the ideal gas law holds throughout the system. The terms a(z)/& and S’(U$Yi)/& will both be zero when the average is for a long time period. Gas mole fractions entering and leaving are 0.009 and 0.001.

Analyze the assumptions of constant temperature and LIG rate for the column. 13- 7. The initial and boundary conditions are: atz = -w, cI = cp atz = +w, CII = cPI The first boundary condition at z = 0 is the statement of equilibrium at the interface, m being the "distribution coefficient" or "Henry's law constant." In carrying out this analysis, note that it is important to consider each term and to justify its nonapplicability.

The understanding of gas-solid kinetics is crucial to the study of heterogeneous catalysis and integrated circuit fabrication. In 1949, Mysels received a patent on this type of friction-reducing additive [M13]. Upon a second integration, Eq. (4.88) becomes -pu, = (&/2)(y2) + ClY + c2 (4.89) The velocity of the fluid is zero at each plate. D. in Chemical Engineering from the University of Pennsylvania. Broer (personal communication, 20 August 1958). 330 Chapter 10 Shell Energy Balances and Temperature Distributions in Solids and Laminar Flow Now introduce the dimensionless quantities 6 = r / R and B = kJ?.2E2/k,,~2~o and show that Ea. 10C.l-3 then becomes When the power series expressions for the conductivities are inserted into this equation we get This is the equation that is to be solved for the dimensionless temperature distribution. (b) Begin by noting that if all the ai and Pi were zero (that is, both conductivities constant), then Eq. 10C.l-5 would simplify to When this is solved with the boundary conditions that @ = finite at 4 = 0,-and O = 0 at 5 = 1, we get 0 = $B(l - f ) (lOC.l-7) This is Eq. 10.2-13 in dimensionless notation.
