3. Consider a simple 3-component flash separation system as illustrated by the process flow

sheet below. The feed could contain hexane, heptane, and octane. Here, i
F stands for the

inlet mass flow rate of stream i (e.g., in kg/hr) and inj is the mass fraction of species j in

stream i. Using matrix calculation, compute for the mass flow rate for each outlet stream

that can be denoted as x1, x2, x3. (
