For remote controlling and monitoring, the energy distribution units according to Figs 6.105 and 6.107 are fitted with coupling elements to intrinsically safe electric circuits. 

A way of looking at the points raised in the previous section is to compare energy distributions in two systems whose free energies we wish to relate. In particular, consider measuring, in a simulation of system 0, the fiinction Pq(AE), i.e., the probability density per unit AE of configurations for which and differ by the... 

Theoretical mathematical expression of energy measurement related to the second law of thermodynamics. Essentially a measurement of relative quantities of energy distribution, and reported in units of Btu/lb. or J/kg.

Because the rotating motion of the gas in the cyclone separator arises from its tangential entry and no additional energy is imparted within the separator body, a free vortex is established. The energy per unit mass of gas is then independent of its radius of rotation and the velocity distribution in the gas may be calculated approximately by methods discussed in Volume 1, Chapter 2. 

This is Planck s famous radiation law, which predicts a spectral energy density, p , of the thermal radiation that is fully consistent with the experiments. Figure 2.1 shows the spectral distribution of the energy density p for two different temperatures. As deduced from Equation (2.2), the thermal radiation (also called blackbody radiation) from different bodies at a given temperature shows the same spectral shape. In expression (2.2), represents the energy per unit time per unit area per frequency interval emitted from a blackbody at temperature T. Upon integration over all frequencies, the total energy flux (in units of W m ) - that is, Atot = /o°° Pv Av - yields... 

With bonded, NP-HPLC sorbents, such as the porous aminopropylsilica sorbents, the distribution constant, abSii, can be equated with the solubility parameter, 6, which in turn is a measure of the intermolecular interaction energy per unit volume of the polypeptide in a pure liquid such that... 

Multiplication of P by the number of electrons arriving at unit surface in unit time should then give the field emission current density J. The argument just presented has limited itself to electrons at the top of the Fermi sea. It is apparent from Equation (1) and the nature of the electron energy distribution that this assumption is good.

Solar radiation consists of photons of different energies E. Of particular interest is the spectral distribution n(E), which describes how the photons are distributed over the different energy values. The quantity n(E) indicates the number of photons of specific energy E per unit surface area per unit energy per unit time. From this distribution we define the total photon flux as... 

This result describes quantitatively the energy distribution of the decaying nij hole-state. The function is symmetric in E around En(j. For E = E (j it has a maximum, and its fwhm value is given by En(j which is called the natural or inherent level width because it originates from the decaying hole-state which is inherent to the atom. As an example, a compilation of level widths r in neon is given in Table 2.2. Because of the replacement made in the derivation of equ. (2.18b) for xn(, one has (in atomic units)...
