Problem 1: a) A solution that contains nitromethane in acetonitrile is heated at constant pressure of 1 bar until the first bubble appears. If the temperature at this point is 85 °C, what is the composition of the original solution? b) You are delivered a mixture of nitromethane in acetonitrile. The composition is not known but you are told that the dew temperature at 1 bar is 93.5 °C. What is the phase at 111 °C, 2 bar? Problem 2: At 80 °C, 1.32 bar the system methanol(1)/ethanol(2) is in vapor-liquid equilibrium. The composition of the two phases is x1 = 0.25, y1 = 0.37. Calculate the fugacity, fugacity coefficient of each component in each phase. You may assume that the vapor phase is in the ideal-gas state.
Why fluids are important in chemical engineering - enormous number of materials normally exist as gases or liquids, or can be transformed into such phase and explain systematic description of change in fluid systems, mechanical change
Rebecca believed that Stogy would be able to hire experienced cigar rollers whose output would be somewhere around 200 cigars a day, depending on the cigar's size and shape as well as on the roller's skill.
