Fracking is defined as the process which entails drilling down into the earth surface. The drilling is done before the high-pressure water is channeled towards the rock with the aim of aiding in the release of the gas inside. Sand, chemicals, and water are, therefore, injected into a particular rock coupled with high pressure to enable efficacy in the flow of gas out to the head of the well. It is worth noting that the working of fracking entails several steps. The first step is on drilling a…

OBJECTIVE: To study the chemistry behind “LIQUID LUBRICANTS: MECHANISM OF ACTION AND APPLICATIONS”. ABSTRACT: Various books and literatures provided information regarding the application of chemistry in an important and interesting area i.e. lubrication. The literature imparted the following information regarding the liquid lubricants: Lubricants are the substances that that are added to reduce friction between two surfaces. Friction is simply defined as an opposing force that comes into play…

wanted to identify what the four mystery liquids were using density and their characteristic properties. We were initially given four liquids that were labelled numbers 1- 4, some graduated cylinders, and a scale, but we also knew that the 4 liquids were ethanol, vegetable oil, water, and cyclohexane. Using the mass that we found when we measured the liquid and using only 10 mL of the liquids we were able to calculate the density and easily identify the liquids and see if they matched the…

Clear Liquid Diet, Pediatric A clear liquid diet is a diet that includes only liquids that you can see through. Your child may need to follow a clear liquid diet if he or she has an upset stomach or is going to have a certain procedure or test. The goals of this diet include: To rest the stomach and digestive system as much as possible. To keep your child hydrated. To make sure your child gets some calories for energy. Most children need to follow this diet for only a short…

Experiment 2: Aim: In this experiment you will determine the mass of a single drop of water by a graphical method. You will evaluate its uncertainty. Data: Table 1: Number of Drops: Mass of Beaker + drops/g (0.01g) 1 2.36 g 2 2.38 g 3 2.40 g 4 2.44 g 5 2.46 g 6 2.48 g 7 2.50 g Chart 1: Analysis: The mass of 1 drop of water is 0.4g. By taking the total mass and dividing it by the number of drops we can figure out the average mass of a drop of water. However the number of drops should…

This project consist of Numerical and Computational Fluid dynamics analysis of heat transfer enhancement and the corresponding pressure drop over a flat surface equipped with cylindrical cross-sectional perforated and solid pin fins in a rectangular channel. The channel had a cross-sectional area of 250-100 mm2. The experiments covered the following range: Reynolds number 13,500–43,500, the constant clearance ratio (C/H) = 0, the inter-fin spacing ratio (Sy/D) 1.944 and 3.417 for Staggered…

There are two methods you can use to find out how porous your hair is: A. The Float Test: Take a couple of strands of hair from your comb or brush and drop them into a bowl of water. Let them sit for 2-4 minutes. If your hair floats, you have low porosity. If it sinks, you have high porosity. B. The Slip'n'Slide Test: Take a strand of hair and slide your fingers up the shaft (toward the scalp). If you feel little bumps along the way, this means that your cuticle is lifted and that you have high…

Discussion: Water was transferred from burettes and pipettes to a beaker, in order to see how accurate and precise these instruments would be. The displacement of the burette would be the measured volume of the water. Similarly, the water from the 5.00mL or 10.00mL pipette was transferred to a beaker. The beaker w/ water mass and the initial mass of the beaker was subtracted to obtain the grams of water in the beaker. Using the temperature of the water, the density could be found, allowing…

You can lay concrete during the winter; however, you need to be careful. Here are a few precautions that you need to take while laying concrete during cold weather. #1 Never Lay Concrete On Frozen Ground The key to laying concrete during the winter time is to never lay it when the ground is frozen or on top of snow or ice. When you lay concrete on frozen ground, the coldness will transfer to the concrete and will slow down the drying process. Additionally, when the ground thaws, it will…

Probably the most difficult deposit to deal with is deep, wet snow when ambient temperatures are slightly above the freezing point. This type of deposit should be removed with a soft brush or squeegee. Use care to avoid damage to antennas, vents, stall warning devices, vortex generators, etc., that may be concealed by the snow. Light, dry snow in subzero temperatures should be blown off whenever possible; the use of hot air is not recommended, since this would melt the snow, which would then…
