4.6 The Selection of the Injection Machine
4.6.1 Calculation of the Injection Volume
Figure 4-8 shows the volume of plastic parts by Solidworks modeling.
Figure 4-8 Volume of the Stress Cone
Plastic parts volume: Vplastic = 4.198 × 10-5 m3 = 41.98 cm3
Plastic parts density: ρ = 1.2 g/cm3
Plastic parts quality: mplastic = ρVplastic = 1.2 × 41.98 = 50.376 g
4.6.2 Preliminary Estimation of the Gating System
Although the gating system of condensate cannot determine the exact value prior…
Fig.3 illustrates that the unsteadiness parameter reduces the dimensionless film thickness . Also, for critical value of the unsteadiness parameter the film thickness tends to zero. This implies the film thickness vanishes that this critical value and then the motion becomes impossible.
One of the main objectives of this study is to discuss the surface tension effect, according to thermosolutal Marangoni convection effect, on the motion. The increase of the temperature surface tension…
separating liquids with 2 different boiling points. Distillating requires heating and cooling of liquid components to eventually purify the mixtures. In distillation, heat is added to vaporize the liquid with the lower boiling point and this vapor gas bubble is condensed back into its liquid form, where it is then collected in a receiving flask or a graduated cylinder. Multiple distillations and collections, depending on the types of distillation techniques, yields distinct, separated liquids.…
A fraction containing primarily cyclohexene primarily cyclohexene and water is separated from raw cyclohexanone in Cyclohexene column. Raw Cyclohexanone is fed from storage tank to Cyclohexene Column via Cyclohexene heater.
In Cyclohexene Heater, the feed is heated up to about 1200C with the heat carried by the bottom product from Alcohols column. The Cyclohexene column is operated at atmospheric pressure and temperatures of 850C at top and 1650C at bottom. The vapours…
fixed mass of gas held at a constant volume, which pressure divided by temperature is a constant value. The gas has initial pressure and final pressure of Pi and Pf respectively, and initial temperature and final temperature of Ti and Tf respectively. Therefore, the equation below is obtained:
Pi = Initial pressure
Pf = Final pressure
Ti = Initial…
states that a substance can exist as. A gas does not maintain shape and volume. Gases expand to fit and fill the container. While a liquid maintains volume, but not shape and fits the shape of the container it is placed in. Solids can maintain both volume and shape. When a gas exerts force on the walls of a container, this is known as its pressure. Pressure varies based on temperature and volume.
Many gas laws were used within this experiment, such as the Ideal Gas Law, Boyle’s Law, Charles’s…
shown in the figure below, compressibility increases linearly as pressure decreases from 2500psi to the bubble point. At the bubble point, as pressure decreases now the compressibility increases exponentially. The change in gradient occurs as there is gas present in the fluid.
1873. The van der Waals EOS gives a simple, qualitatively accurate relation between pressure, temperature, and molar volume.
where a is “attraction” parameter, b is “repulsion” parameter, and R is universal gas constant. Comparing this equation with the ideal gas law,P= zRT/v, we see that the van der Waals equation offers two important improvements.
The prediction of liquid behavior is more accurate because volume approaches a limiting value 'b' at high pressures i.e,…
The CEO of a large perfume factory needs to know the best way of safely transporting n-hexanol, which is used in manufacturing perfumes, to his factories. Therefore, the purpose of this experiment was to find the most beneficial way to transport an alcohol. Specifically, if transporting n-hexanol in hot or cold temperatures works best or if another alcohol should be used. A volatile liquid is a liquid that evaporates readily at room temperature or a liquid that has a measurable vapor pressure…

Enzyme I: pH and Temperature Lab Report
(2008, November 11). Without Enzyme, Biological Reaction Essential To Life Takes 2.3 Billion Years. Retrieved January 31, 2017. The basic concept that is being explored are about enzymes. Enzymes are proteins that are known for being sparkplugs in a chemical reaction. Enzymes have a shape and for them to ‘spark’ they must have the proper substrate for it to work U. This does not change the enzyme’s…
