1. A liquid process stream containing benzene and toluene leaves an extraction unit and flows into a pipe. At the entrance of the pipe the cross-sectional area is 0.179 m2, total mass flow rate, m ̇, is 117.4 kg/min, and the stream contains 44.7% benzene by mass. The cross sectional area of the pipe increases to 0.247 m2 at the exit. The density of the liquid is constant and the SG is 0.874. Find the: a. mass flow rate, m ̇ (g/s), at the exit. b. the apparent velocity of the mixture at the entrance, v in (m/s), and exit, v out (m/s) c. The mole fraction of toluene in the exit stream.

1. A liquid process stream containing benzene and toluene leaves an extraction unit and
flows into a pipe. At the entrance of the pipe the cross-sectional area is 0.179 m2, total
mass flow rate, m ̇, is 117.4 kg/min, and the stream contains 44.7% benzene by mass.
The cross sectional area of the pipe increases to 0.247 m2 at the exit. The density of the
liquid is constant and the SG is 0.874. Find the:
a. mass flow rate, m ̇ (g/s), at the exit.
b. the apparent velocity of the mixture at the entrance, v in (m/s), and exit, v out (m/s)
c. The mole fraction of toluene in the exit stream.
