The gap-filling processes were then observed for different combinations of extrusion temperatures and feed rates. A criterion was first developed to determine whether the gap was filled at a specific location of the tube. The glass tube functioned as the extruder in our case. In this work, the gap-filling processes of Acrylonitrile Butadiene Styrene (ABS) and Polylactic Acid (PLA) filaments were directly observed through a heated glass tube. On the other hand, it is important to know this information, for example, to model the distributions of temperature and pressure during the extrusion. It is still not clear how this gap is filled during the extrusion. There is a finite gap between the inner surface of an extruder and the edge of a filament, which facilitates the insertion and translation of the filament inside the extruder. I also learned that accurate information is very crucial in experiments like this.In material extrusion (MatEx) additive manufacturing, solid polymer filaments are fed into extruders to generate extrudates that are needed to build 3D plastic parts.

I also learned how to find the vapor pressure of water and how to use the slope of a graph to solve a problem. As it cools the volume of air contracts and there becomes less water vapor. I learned that air expands as it is heated and becomes saturated with water vapor. If these are all too high then the equation for slope will be too high finally causing the enthalpy of vaporization to be too high. The volume being too high would make the adjusted volume, pressure of the cylinder, partial pressure of the air and water to be too high also. This would make the volume of gas to be too high because it isnвЂ™t all air that is in the cylinder. Another source of error is that there were bubbles of water stuck to the side of the graduated cylinder as it was upside down in the beaker. Our data could be too high or too low now causing the overall equation for slope to be wrong resulting in the enthalpy of vaporization to be off. Like the amount of water in the beaker in the first place and the amount of gas in every temperature interval. This is not accurate because everything was different from ours. We didnвЂ™t have time to put ice in our beaker to record the temperature and volume, which is a major source of error because we had to use somebody elseвЂ™s data. Therefore, the enthalpy of vaporization of water will be t00 low. This would affect the volume measurements and cause the adjusted volume and the partial pressure of air and partial pressure of water to be lower than it should be. The air in the graduated cylinder could have escaped because of the space between the graduated cylinder and the beaker. Hexane has a lower enthalpy of vaporization than water. 46 |Temperature (oC) |Partial Pressure of H2O (mmHg) | |80 |652. Table of vapor pressure of water at each temperature.Д®x: 774. 2 | |Temperature (oC) |Partial Pressure of H2O (mmHg) | |60 |631. 5 | |Temperature (oC) |Partial Pressure of Air (mmHg) | |60 |142. 3 mmHg |Temperature (oC) |Partial Pressure of Air (mmHg) | |80 |121. List of all calculations for each temperature and the adjusted volume using the number of moles calculated in #3. The number of moles of air in the graduated cylinder at 0oC is: (774.

When the beaker reaches 50oC add ice to cool it to 0oC. Cool the beaker until the temperature reaches 50oC recording the temperature and volume every 5oC. Heat the beaker until the water is about 80oC and record the temperature and the volume.

Measure the difference between the height of the water in the graduated cylinder and the height of the water in the beaker. Make sure the graduated cylinder is under the surface of the water. Cover the graduated cylinder by putting your finger on top and place the cylinder in the 1000 mL beaker.

Next fill a 1000 mL beaker ? full with water. Take a10 mL graduated cylinder and fill it with 7 mL of water.
