Please solve and I will rate answer
A gas stream containing acetone in air flows from a solvent recovery unit at a rate of 142 L/s at 150°C and 1.3 atm. The stream flows into a condenser which condenses most of the acetone, and the liquid and gas outlet streams are in equilibrium at -18°C and 5.0atm. Shaft work is delivered to the system at a rate of 25.2kW to achieve the compression from 1.3 atm to 5.0 atm. To...
