Use results of Sec. 14.6 to develop the following (approximate) rules of thumb:
(a) The solubility of a solid in a liquid solvent increases with increasing T.
(b) The solubility of a solid in a liquid solvent is independent of the identity of the solvent species.
(c) Of two solids with roughly the same heat of fusion, that solid with the lower melting point is the more soluble in a given liquid solvent at a given T.
(d) Of two solids with similar melting points, that solid with the smaller heat of fusion is the more soluble in a given liquid solvent at a given T.

Volume of Air Required for Combustion of a Natural Gas Mixture, A natural gas has the following analysis by volume:
Equation (13.65) represents a recursive relationship between a sequence x[n] and its complex cepstrum [n]. Show from Eq. (13.65) that the characteristic system D∗[·] behaves as a causal system for minimum-phase inputs; i.e., show that for minimum-..
Momentum fluxes for creeping flow into a slot (Fig. 3.B-7). An incompressible Newtonian liquid is flowing very slowly into a thin slot of thickness 2B (in the y direction) and width W (in the z direction)
-12 the gravimetric composition and properties of two different typical fuels i.e. coal and fuel oil is tabulated below- Parameters coal fuel oil Composition weight% -- C 76 85 H 4.5 11.5 S 0.5 3.5 N 1.0 -- O 3.0
Styrene is made by dehydrogenation of ethyl benzene, which is formed by alkylation of benzene with ethylene. Propose target yields for the alkylation and dehydrogenation steps if the forecasted prices per metric ton are styrene $800, ethylene $800..
Which of the three variables above currently limits the EQE of quantum dot-based LEDs to about 1%? Why are all-inorganic devices desirable rather than hybrid organic-inorganic devices?
The column will operate at 1.1 bar and ambient temperature. If necessary, the aqueous stream may be recirculated to maintain a suitable wetting rate.
A distillation column separates benzene from toluene using a control scheme similar to that shown in Figure (a). Make a practice HAZOP study of the plant section and add any instrumentation that is needed to develop the full P and I diagram.
The total series-field and armature-circuit resistances are 25 and 50 m Ω, respectively. The core loss is 220 W; friction and wind age loss is 40 W.
Product X takes 1 machine hour per unit and Product Y takes 5 machine hours per unit. Which of the following is one of the constraints for this linear program?
Assuming the analyses are accurate, what do they show about the ratio by weight of each of the three fractions actually obtained? What is the overall effectiveness of each screen?
