One might visualize that a two-phase region in a binary diagram is made up of an infinite number of horizontal (isothermal) tie-lines. Using the average alloy composition as a fulcrum (x) and applying the Lever Rule, it is quickly possible to derive mass ratios and fractions. For instance...
Enthalpy of an ideal gas is dependent only on temperature and is expressed by Eq. (6.3-18). Therefore, in problems involving ideal gases, variation in pressure has no effect on the enthalpy change. In the case of incompressible fluids, Eq. (6.3-12) reduces to (6.3-22)H^=∫TrefTC^PdT...
In addition, the effect of temperature has been presented as an influence for structural phase transformation of boron carbides such as BC1.6 and BC3, while the phase diagram boundaries of the boron carbides are still incomplete. Keeping all these carbon-rich in mind, another class of carbides, ...
where u is an excess pore water pressure, t is the time, cv is the coefficient of consolidation and z is the vertical coordinate. The derivation of this equation is systematically presented in most of the soil mechanics textbooks that appear on the publishing market [12, 152, 234]; thus,...
During this work, we demonstrate, for the first time, that the volumetric properties of pure ionic liquids could be truly predicted as a function of temperature from 219 K to 473 K and pressure up to 300 MPa. This has been achieved by using only
Since the velocity is the same as that of a free molecule, the pressure will be the same as the pressure of an ideal gas of the same molecular concentration. Hence, the osmotic pressure π, is given byvan't Hoffformula[4], which is identical to the pressure formula of an ideal gas:...
14. The method of claim 11, wherein said wellbore pressure has a friction component due to fracture tortuosity and tubing friction, and wellbore includes tubing having a tubing friction component, and further comprising an estimation of said friction component of the monitored wellbore pressure. ...
Stagnation pressure refers to the high values of pressure measured at the nozzle and Pitot probe in high enthalpy facilities using piezoelectric pressure transducers. It is an important parameter in aerodynamic studies to understand the impact of flow on models and surfaces. ...
This is potentially an important issue for the derivation of trends, as radiosonde changes may therefore introduce vertical shifts in the ozone profile, and apparent changes in ozone concentration at a given height. A number of different radiosonde designs, from several manufacturers, have been used...
[11] established an analogy between the failure of unidirectional carbon fiber-reinforced epoxy plates and filament-wound carbon fiber composite pressure vessels. Using multiscale modeling, they revealed that composite failure was driven by fiber breakage, and that the clustering of fiber breaks ...
