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…

molecules are going to be less dense. When using only the ice cubes the molecules are going to be closer together which will increase the molecular count onto the soda. This should also help it cool the soda faster. Whereas, that molecules of a cold liquid mixed with ice cubes are more compact which makes it a more dense of a substance. This may give an advantage to the ice water. Because it is the most dense, it means the molecules are closer together. This also means that more molecules are…

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…

A filter is something that removes impurities or solid particles from a liquid or gas that passes through it. There has been a total of 76% of deaths due to infections from dirty liquids and poisonous gases. Not many filters do the same job you would like it to do, but with this particular filter it is made to filter out gases, liquids, and solids from a variety of different elements and objects as well as cleaning any object you toss into it. The item's frame is powerful enough to do these…

Frigidaire FFA 7033 1 Review An excellent dehumidifier will protect your home from any mold, fungus or mildew growing and wrecking havoc. This dehumidifier delivers in any wet environment, and prevents pollutants from getting in the air. You’ll be able to breathe easier, and not have to worry about contaminants. The reservoir for the dehumidifier holds up to 70 pints of moisture a day, allowing you to spend less time dumping the moisture out. If you place it by a drain, you can start it up,…

Wastewater is Ms. Brown's main topic of discussion in this article. The effects on drinking water, landfills and wastewater treatment facilities are outstanding and a poor representation of what is being done to regulate fracking practices across the country. This pushes it's readers to think twice about the water they are drinking and what is really being done for the peace of mind of the rural citizen. With case-by-case interviews of people in the field of wastewater treatment and maintenance…

like dust particles or a feather. Part B, we used onions, blue methylene and water. It's called a “Wet Mount” since we used a liquid substance (blue methylene and water).Wet mounts are used with a piece glass concave slide and a solid object for viewing it. A drop of water or other liquid substances is dropped onto the object and a cover slip is slid on top of the liquid. The tension of the surface of the water automatically will close the cover tight to the slide while still holding the object…

Research Question: What is the effect of the properties of a mixture on the methods of separation and the mass of each substance that is obtained after separation? Background Research: What is a mixture: The reason for the chosen methods: Water is able to dissolve salt because the water molecules (H2O) attracts the sodium(Na) and chloride(Cl-) ions. Hypothesis: If we use a magnet to separate the iron from the mixture we will only extract the iron from the mixture because nothing else in…
