1. Consider a mixture that contains 60% water (species 1) and 40% methyl alcohol (species 2). Determine the spinodal curves for the mixture as a function of pressure and temperature. Assume that the mixture follows the RK equation of state.
2. Water boils with the mother liquid phase at 593 K and 133 bar. The vapor embryo is at the same temperature as the liquid, but at a different pressure. Assume that the RK equation applies and that the vapor pressure is 155 bar. (According to the RK equation of state, for water Psat?=?133 bar at 593 K.) Determine the bubble size. Assume that the surface tension σ?=?10.5 ×?10-6 kN m-1 .
