The catalyst bed that was charged to the reactor is now a restriction, calibrated for flow vs. pressure drop. The pressure drop equals the pressure generated by the blower, which in turn depends on the RPM. In essence, the differential pressure measurement was eliminated by calibrating the flow directly with RPM.

Nutter [99] reports that most, if not all structured packing (Figures 9-6LL and 9-6MM) follow the linear relationship of vapor rate vs. pressure drop at fixed liquid rates as exhibited by random packings.

The diode laser is scanned up and down in frequency by a triangle wave, so that the scan should be linear in time and have the same rate in both directions. In the thermal accommodation coefficient experiments, the external beam heats the microsphere to a few K above room temperature and is then turned off. The diode laser is kept at fairly low power ( 7 pW) so that it does not appreciably heat the microsphere. Displacement of a WGM s throughput dip from one scan trace to the next is analyzed to find the relaxation time constant as the microsphere returns to room temperature. Results from the two scan directions are averaged to reduce error due to residual scan nonlinearity. This is done over a wide range of pressures (about four orders of magnitude). The time constant provides the measured thermal conductivity of the surrounding air, and fitting the thermal conductivity vs. pressure curve determines the thermal accommodation coefficient, as described in Sect. 5.5.2. 

The intercepts in plots of flow rate vs. pressure were at slightly positive values of overpressure, and as expected, the least viscous solvents showed the highest flow rates at a given pressure (Fig. 6). Vertical error bars are included, but they are almost too small to... 

The pressure dependence of (3P/3v) can be tested by fitting [(3P/3v)P - (3P/3v) ]/P vs. pressure. It is clearly shown in Figure 14 that the values of [(3P/3v)p - (3P/3v) ]/P for pure water and 35 °/oo salinity seawater determined from sound speed data (112,123),increase almost linearly with pressure. This indicates that P or even higher order terms are needed to represent (3P/3v) over the pressure range of 0 to 1000 bars. In other words, the Tammann equation and the original Tait equation do not represent the PVT properties for pure or saline water within the accuracy of the data.

In all the techniques described here, it is assumed that the shock wave is plane and parallel to the wedge-and-attenuator interface. The initial shock and particle velocity vs pressure in the wedge are obtained from a graphical solution involving the wedge density, early average shock velocity, and pressure in the... 

The condition for valid results in this work is the fact that the system is in the gel-state that is, it is in a state of inner equilibrium, and not in the glass state. Measurements of Hellwege, Knappe, and Lehmann (5) on pure PVC show the expected discontinuity in the compressibility vs. pressure curve at the melting point transition in the glass state. It is inferred from this study that the glass temperature for pure PVC and for the plasticized, gel-type PVC does not rise above 110° C. at pressures of 200 atm. (Figure 7). Our study showed that the system is always in a state of inner equilibrium. 

The development of the reaction was followed by measuring pressure change (Ap), light emission (7), reaction rate (dAp/dt), and by chemical analysis. Pressure rise was recorded by a pressure transducer (A.C.B. 504H). Reaction rate (dAp/dt = W) was obtained by using a resistance-capacity circuit of suitable time constant, 6 = RC (76, 78), appropriate to the branching factor of the reaction, < . It was possible to record simultaneously pressure rise vs. time and rate vs. time or rate vs. pressure rise.
