The results found in the collated table supports the hypothesis, however, it was not as accurate as expected. From observation of the collated results, it can be seen that the greatest froth volume is found at 30oC, rather than the predicted optimum temperature of 39oC. Errors within the individual group results, concluded that the both 10oC and 20oC were wrong due to the vast froth volumes. For a smaller amount of catalase, this would result in a smaller froth volume, conversely, with a greater…

Emulsions are mixtures that contain two or more substances that cannot combine to make homogenous mixtures. One of the liquids contains dispersions of the other substances. The emulsions are formed from shaking the substances vigorously to counteract the different densities of the substances. The extra substances added to the emulsions beside water and oil are refered to as emulsifiers. The emulsifiers are substances added to keep the oil from separating completely from the water. Emulsions are…

Discussion: In sample, B there was 16% salt, which is unnaturally higher than the global average of 3.5%. When I asked about the reason of this, I found that the water was artificially created. This was also the case of Sample, A which had 9% of salt. That is about 3x the amount of salt from the global average. All though this is not an experiment with data, that we can apply to real life, it was still great fun to do the experiment and the lessons I learnt will stick with me for a long time.…

in such a manner that prevented emerged bubbles that could have formed disrupting test accuracy. o Temperature of the liquid was collected once the fluid was in the cylinder. 3. Dropped into the cylinder was a Glass (Dark) ball then a Steel (Silver) ball twice for a total of four trials. o Each ball was fished out smoothly from the oil to be removed with a hook utensil. o The liquid was drained out about halfway back into the measuring cup at a slightly incline manner pouring slowly. 4. Slow…

Paintball is a game that shoots out markers or paintballs, that when they hit, the markers explode causing a paint mark on a person, a piece of cover, and trees.Paintball is also a game where many people do different types of games like capture the flag to different battle scenarios. Before paintball was a game paintballs was used to mark cattle for shipping purposes. Many people play this game with pump guns. These guns have an air pump attached and also a hopper.The hopper is the top piece of…

of 3M HCl was added and swirled into the solution. The top of the 25-mL flask was capped and the two liquid were mixed in a thorough manner. Ventilation was required after every few seconds. After letting the solution sit for a while and letting the liquid layers separate,…

CHAPTER 1: BACKGROUND 1.1 ENHANCED OIL RECOVERY Oil production is differentiated into three stages: primary, secondary and tertiary, which is also known as Enhanced Oil Recovery (EOR). Primary oil recovery is restricted to hydrocarbons that naturally produced to the surface, or those that utilization artificial lifts, for example, pump jacks. The secondary recovery utilizes water and gas injection, dislodging the oil and driving it to the surface. US Department of Energy stated that by using…

A drill pipe non-return valve (NRV) is essential in MPD operations. A U-tube analogy demonstrates that any positive unbalance in the annulus will result in forcing fluid up the drill pipe. [4] Referred to as a float, the NRV is usually driven by a piston. During circulation, drilling fluid forces the valve open against the spring. When pumps are off the valve is closed through a combination of the spring and wellbore pressure. [2] Figure 2.7c Rig layout for MPD operations (KCA Deutag Source…

Therefore, the three-dimensional unsteady heat conduction differential equation is: where T (x, t) is the temperature of the spot x at the time t and is also the coefficient of thermal diffusivity used to measure the heat transfer and storage ability of the material, which varies with temperature and position. Equation (5) gives the form of three-dimensional heat transfer function. It is generally difficult to find the analytical solution because of the complexity of the actual solution…

HOW JCB MACHINE WORKS The Basic Idea of Hydraulics: The basic idea behind any hydraulic system is very simple. Force that is applied at one point is transmitted to another point using an incompressible fluid. The fluid is almost always an oil of some sort. The force is almost always multiplied in the process. If two pistons fit into two glass cylinders fitted with oil and connected to one another with an oil-filled pipe. If you apply a downward force to one piston(suppose the left one), then…
