Composition of Streams Connected to a Flash Vaporization Unit

A feed stream to a flash vaporization (FV) unit contains water (30%, mole) and acetone. The feed flow rate is 1000 mole/min. The mixture is sent to a continuous flash vaporization unit at atmospheric pressure where 50% of the solution leaves the unit as vapor. The liquid stream from the flash vaporization unit is sent to a second FV unit. The liquid stream leaving the second unit contains 10% (mole) acetone.

a) Determine the composition of streams leaving the first FV unit.
b) Determine the amount of liquid and vapor leaving the first FV unit.
c) Determine the amount of streams leaving the second FV unit.
d) What is the composition of the vapor stream leaving the second FV unit?
e) Calculate the total recovery of acetone from this process.

The attached file shows a simplified circuit for a photographer's flashunit.
The circuit consists of a 9 V battery (V) connected to a 55 kΩ resistor (R), a 140 μF capacitor (C), and two switches (S1 and S2).
Initially, the capacitor is uncharged and the two switches are open. To charge the unit, switch S1 is closed. T
