At time zero, the temperature of face 2 is 320 K. (a) Find the rate of accumulation in J s-r. (b) Find the equation for the temperature profile and determine the temperature at face 1 at time-zero and after 104 s. 3.2. Compare and contrast forced convection and free convection, with regard to methods of problem solving, dimensional analysis, and occurrence in industrial and meteorological prob- lems. 6. Note that the shear stress is subscripted with two letters. nonattracting.

To get 8, as a function of x,,, we may use Fig. 22.8-7, or use Eq. 20.1-17 to write 8, = (1 - xAO)+(xAO) (penetration model) (22.8-41) where +(xAO) is the quantity defined just after Eq. 20.1-22 and given in Table 20.1-1. (b) The stagnant-film model. Laminar Tube Flow with Constant Heat Flux at the Wall: ~~~~~~i~ solution For small z the heat addition affects only a very thin region near the wall, so that the follow- for the Region ing three approximations lead to results that are accurate in the limit as z + 0: a.

In Eq. (2.5), the double subscript on the shear stress, i.e., rrX, implies that there must be other components of the shear stress (see Section 2.4).

ISBN: 0-471-43819-7 The equilibrium stage approach is applicable to other separation processes (absorption, extraction, leaching, etc.) as pointed out in chapter 12. Material covered includes: Asymptotic expansions.

The phenomenon of drag reduction is a strong function of the molecular weight of the additive [Fl, H2]. Because of the symmetry around the z-axis, the resultant force will be in the z direction. Calculate the steady-state mass flux jAy of helium for the system of Fig. 17.1-1 at 500K. Here po is the vis- Falling Film with cosity at the surface of the film and a is a constant that describes how rapidly p decreases as x Variable Viscosity increases.

If the force on the bottom plate were in the same direction as the force on the top plate, it follows that the force available in the shear stress term would be diminished.

However, if any quantity such as U’ is squared before it is averaged (e.g., u:‘), that average will be non-zero because each value of U:” is never less than zero. Equation (7.96) is exponentiated and the substitutions made: p =760exp K (1545)(%0357) = 760 exp(-0.939) = 297.16Torr 545.67 545.67-(0.00357)(25000) >I (ii) (iii) The temperature at 25 000 ft is calculated from Eq. (7.94): T=545.67-(0.00357)(25000)= 456.42=‘R= -325°F Note that Mount Everest is more than 29000ft above sea level; hence the pressure is even lower at that location. 7.3 RECAPITULATION In this chapter are the detailed balances on a fhrite volume, rather than on a differential volume, as was done in the early chapters.
