<ol> <li>Kj from ideal fluid behavior (low pressure) - applicable for ideal fluids at low pressure. 2) Kj from charts and graphs - using graphical representations to determine Kj. 3) Kj from measurement of a given mixture at a given temperature and pressure - the best way to find Kj if possible. 4) Kj from various empirical equations (McWilliams, Standing, and Wilson) - using empirical equations to calculate Kj. 5) Kj from measurements at a constant temperature and various pressures estimated at different pressures (Hoffman method) - estimating Kj at different pressures.</li> </ol> Signup and view all the answers

<p>The equilibrium ratio for ideal fluids is applicable at low pressure. It represents the ratio of the mole fraction of component j in the vapor phase, $y_j$, divided by the mole fraction of the same component j in the liquid phase, $x_j$ : $K_j = rac{y_j}{x_j}$. It is applicable when dealing with ideal fluids at low pressure.</p> Signup and view all the answers

<p>The equilibrium ratio, $K_j$, represents the ratio of the mole fraction of component j in the vapor phase, $y_j$, divided by the mole fraction of the same component j in the liquid phase, $x_j$ : $K_j = rac{y_j}{x_j}$. It is significant in calculating the phase behavior of a system and the composition of each phase.</p> Signup and view all the answers
