Since the extraction temperature of acetic acid extraction prior to terephthalic acid production are desired at T = 313.2 K and atmospheric pressure. The temperature has been carried out since the aqueous solution that fed to extractor column is originally coming from the top product of distillation column in the upstream process, also keeping the temperature at 313.2 K to avoid the crystallization of acetic acid during the process. Therefore, the experimental liquid-liquid equilibrium data for the quaternary system involving methyl acetate + p-xylene + water + acetic acid at a desired temperature and pressure were performed, as shown in Table 2. The data given in Table 2 were shown as mass fraction. The compositions of the feed mixtures for
Using the three laws any resistance of, current through or voltage across a resistor can be found if any two are already known. The objective of this experiment is to provide proof of these laws. The current and voltage values were measured and placed into KCL and KVL equations to determine whether they turned out as expected. These measured values were then used in the Ohm’s law equation to find resistance. The measured and calculated values were then equated to the expected results from the theories.

Target compounds such as BaCl2, BaCO3, BaTiO3, Ba(NO3)2 and BaSO4 in the fine powder form were filled in Perspex planchet of 1cm diameter. The thickness of these compounds was so chosen to stop all the beta particles. The density of BaCl2, BaCO3, BaTiO3, Ba(NO3)2 and BaSO4 are 3.86g/cm3, 4.29 g/cm3, 3.24 g/cm3 and 4.5 g/cm3, respectively. The various properties such as density and melting point are checked with usual simple methods and found are constant during experiment. The target compound was placed between the detector and the source.
1.0 Abstract Technique for accurate and rapid determination of starch in different type of commercial paper are identified. The commercial paper that has been used in the experiment is Mahjong paper. The main objective for the experiment is to determine the concentration of starch, the percentage of starch and absorbance. The relationship between concentration of starch and absorbance are being determined. Besides that, the Cobb test is carried out to identify the rate of water absorption of the both sides of sample paper.
Equation 1: Absolute Error = Experimental Value – Accepted Value Equation 2: Standard Deviation: Equation 3: Density (ρ) = Mass (m) / Volume (V) Equation 4: General Methods and Materials: In this experiment, the materials used were provided by California State University, Fresno chemistry stockroom. We used a lab coat and lab goggles. The materials used was a 10mL volumetric flask, and an electric balance. Procedure: In order to begin the experiment we need to understand our objectives. Know how to use an electronic balance, calibrate glassware, and know how to use a volumetric flask, calculate density and know how to calculate the percent error.
Centrifugal pumps are known to change the Kinetic energy to hydrodynamic energy. Through various calculations we were able to calculate measurements like the suction side length, height of the tank, K-values which were used to read the bends and fittings and the diameter of the pump. The system curves where plotted after obtaining all the required calculations and overall these helped us verify that the results are correct as they follow on the steps of the theoretical
MTRL 578 Tutorial 1 Report Debanga Kashyap 88851150 Introduction: The objective of this analysis is to study the self-annealing process of copper deposited in interconnects using a resistivity model. The data set provided gives the measurements of voltage and current with time of a four-point probe experiment. A four-point probe based instrument is used to measure the average resistance of a thin film or sheet. The instrumental set up consists of passing a current through the two outer probes and measuring the voltage through the inner probe, thus allowing the measurement of the substrate resistivity. The data provided shows a constant current from the 4-point probe measurement.
The synthetic hydrolysate liquor contained (M) sulfuric acid, 50 g/L xylose, 1.5 g/L and distilled water. 1 g/L of sulfuric acid was used as the concentrate solution at the beginning of an experiment to provide sufficient conductivity to the solution. After removing sulfuric acid from the liquor (diluate solution), the run was paused for 30 min, the electrodialyser stack was washed with copious amounts of water, and the sulfuric acid enriched recovery solution was further passed. Flow rate was varied between 3 and 20 mL/min, whereas, the applied electric potential was kept constant. The results of the effect of feed flow rate on sulfate ions removal were utilized to optimize separation of sulfuric from the lignocellulosic hydrolysate liquor and can be used for further scaling up.
