  2. McCabe–Thiele method - Wikipedia

    en.wikipedia.org/wiki/McCabe–Thiele_method

    For example, if the feed is a saturated liquid, q = 1 and the slope of the q-line is infinite (drawn as a vertical line). As another example, if the feed is saturated vapor, q = 0 and the slope of the q-line is 0 (a horizontal line). [2] The typical McCabe–Thiele diagram in Figure 1 uses a q-line representing a partially vaporized feed.

  3. Cole–Cole equation - Wikipedia

    en.wikipedia.org/wiki/Cole–Cole_equation

    The Cole–Cole equation is a relaxation model that is often used to describe dielectric relaxation in polymers.. It is given by the equation = + + ()where is the complex dielectric constant, and are the "static" and "infinite frequency" dielectric constants, is the angular frequency and is a dielectric relaxation time constant.

    In consequence, the reaction rate constant increases rapidly with temperature , as shown in the direct plot of against . (Mathematically, at very high temperatures so that E a ≪ R T {\displaystyle E_{\text{a}}\ll RT} , k {\displaystyle k} would level off and approach A {\displaystyle A} as a limit, but this case does not occur under practical ...

    The following MATLAB code will plot the root locus of the closed-loop transfer function as varies using the described manual method as well as the rlocus built-in function: % Manual method K_array = ( 0 : 0.1 : 220 ). ' ; % .' is a transpose.

  6. Thermodynamic diagrams - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_diagrams

    Thermodynamic diagrams usually show a net of five different lines: isobars = lines of constant pressure; isotherms = lines of constant temperature; dry adiabats = lines of constant potential temperature representing the temperature of a rising parcel of dry air

  7. Ternary plot - Wikipedia

    en.wikipedia.org/wiki/Ternary_plot

    A ternary plot, ternary graph, triangle plot, simplex plot, or Gibbs triangle is a barycentric plot on three variables which sum to a constant. [1] It graphically depicts the ratios of the three variables as positions in an equilateral triangle .

  8. Log–log plot - Wikipedia

    en.wikipedia.org/wiki/Log–log_plot

    The left plot, titled 'Concave Line with Log-Normal Noise', displays a scatter plot of the observed data (y) against the independent variable (x). The red line represents the 'Median line', while the blue line is the 'Mean line'. This plot illustrates a dataset with a power-law relationship between the variables, represented by a concave line.

  9. Eyring equation - Wikipedia

    en.wikipedia.org/wiki/Eyring_equation

    The general form of the Eyring–Polanyi equation somewhat resembles the Arrhenius equation: = ‡ where is the rate constant, ‡ is the Gibbs energy of activation, is the transmission coefficient, is the Boltzmann constant, is the temperature, and is the Planck constant.
