04: DALTON LAW Nitrogen from a cylinder is bubbled through liquid acetone at 1.1 bar and...
#1 Acetone is to be removed from a nitrogen stream in a process. In the first step of the process, the gas is compressed from 1 atm to 4 atm. In the second step, the gas is cooled at constant pressure to a temperature of 5°C in a condenser. Some of the acetone condenses to liquid in the condenser and the remaining gas leaves the condenser saturated with acetone. The gas fed to the process enters at 40°C and 85%...
Homework 2 Problem 1: A piston-cylinder device initially contains 0.35-kg steam at 3.5 MPa, superheated by 7.4 C. Now the stream loses heat to the surroundings and the piston moves down, hitting a set of stops at which point the cylinder contains saturated liquid water. The cooling continues until the cylinder contains water at 200C. Determine (a) the final pressure and the quality (if mixture), (b) the boundary work, (c) the amount of heat transfer when the piston first hits...
