P-USe

Attributing the measurements in [70WES/GRO] to p-USe2, no experimental thermodynamic information is available for the USe gsCcr) phase. The data for the compound denoted by a-USe2 in [92GRE/FUG] should therefore most likely be allotted to P-USe2 instead. 

The error limits of the entropy were increased in order to incorporate a possible zero-point entropy of 1.17 J-K -moP. These selections agree with the selections in [92GRE/FUG] but there considered to apply to a-USe2. 

Baskin and Smith [70BAS/SM1] measured the enthalpy of formation USe(cr) and U ,Se4(cr) using direct reaction calorimetry and found minor amounts of P-USe2 as a by-product in one of their samples. In order to evaluate their results, the enthalpy of formation of P-USe2 was estimated to be - 426.8 kJ-moP . The measurements were reevaluated by the review as discussed in Section V.13.5.1.1 without using an estimated value, yielding extreme limits for the enthalpy of formation of P-USe2, - 477 kJ-mof 

Af//° (USe2, (3, 298.15 K) - 359 kJ-mol . No value is selected because the P-USe2 phase was only found in small quantities as a by-product. The enthalpy estimated in [70BAS/SMI] was accepted in [92GRE/FUG] and there considered to apply to a-USe2.

In their analysis, Johnson et al. [6] note that, under an applied load P, the aetual eontaet radius a is higher than the radius predieted by the Hertzian theory. Johnson et al. eaieuiate an equivalent Hertzian load P (> P) using Eq. 7, and the corresponding energy U ) stored in the system due to elastic deformation of the sphere under Hertzian conditions. Ui and P are given by... 

In the JKR experiments, a macroscopic spherical cap of a soft, elastic material is in contact with a planar surface. In these experiments, the contact radius is measured as a function of the applied load (a versus P) using an optical microscope, and the interfacial adhesion (W) is determined using Eqs. 11 and 16. In their original work, Johnson et al. [6] measured a versus P between a rubber-rubber interface, and the interface between crosslinked silicone rubber sphere and poly(methyl methacrylate) flat. The apparatus used for these measurements was fairly simple. The contact radius was measured using a simple optical microscope. This type of measurement is particularly suitable for soft elastic materials.

The pressure p used in Equation 3-32 is the differential developed pressure (across the pump inlet and outlet). Since the inlet suction pressure is usually small compared to the discharge pressure, the discharge pressure is used. Thus, this is the application resistance pressure in most cases. Figure. 3-54 shows a typical reciprocating pump performance.
