Question

Problem 2. Phase volumes in a time-dependent two-phase continuous flow sys- tem. Consider a two-phase contacting vessel. In this problem, there are two immicscible liquid phases, but there is no solute mass transfer to be considered. Initially, the vessel contains a volume V = 25,000 L (25 m”) continuous phase (I), and no dispersed phase (II). At time zero, steady flows to the tank commence, with qf = 75 m3/hr and qf1 = 11 mº/hr. Flow exits the vessel via a single pipeline carrying the two-phase mixture. That is, this single exit pipe carries the total exit flow, q = q7 +q71, which is controlled equal to the total feed rate. q=q? +971 = q} + q11 With the tank being well mixed, the volume fractions of the stream leaving the tank are the same as those within the tank: -*9 = KM IL VI 9V VI a) Draw a sketch of the system, labeled with the appropriate variables for the streams and the vessel contents.
