Liquid oxygen

Note this: do not use regular magnets because they do not have the strength to attract the slime. Mix the liquid starch and iron oxide powder in the bowl and stir with the craft sticks until they are mixed perfectly. Add the glue and keep stirring. Take the slime out and start squishing until it is perfectly mixed together. You may wear gloves to avoid staining…

All fluids have its resistance to relative motion between surfaces and is called Viscosity. This property is about the friction between the particles of a fluid. A fluid that is forced in a tube has the liquid moving faster as it is closer the axis of the tube and slower when farther from it. 3.1.1 Dimensionless Parameters In analysis of convection heat transfer, it is convenient to convert to non-dimensional the governing equations and combine the variables, which makes the group of…

Friction loss is defined as the pressure loss or head loss that usually occurs in pipeline fluid flow because of the viscosity effect near the surface of the pipe. When the fluid flows along the pipeline, it produces frictional resistance thus results in loss of energy or total head loss of the fluid. Therefore, experiment was conducted to verify the Darcy Weisbach equation by determining the pressure loss along a horizontal pipe. Figure A below shows the diagram of friction loss along a…

Definition: An orifice plate is a device that is used for the measurement of flow rate for reducing pressure or for the restricting flow. An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. When a fluid (either liquid or gaseous) passes through the orifice, its pressure builds up slightly upstream of the orifice. But as the fluid is forced to converge to pass through the hole, the velocity increases & the fluid pressure decreases. Orifice Plate is the heart of…

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…

the disks would float. Figure 5.1 supports this claim, as there is an almost linear increase in the amount of floating disks over time. The leaf disks in the bicarbonate solution are exposed to enough light, H2O, and CO2 that they can produce enough oxygen to cause floating. If the 0.2% bicarbonate solution were placed in the dark, then the disks…

How to Change Your Oil Frequent oil changes are an important part of routine maintenance (Edmunds). An oil change gets rid of the old oil in the engine by replacing it with new oil (Edmunds). The oil filter is also replaced during this process. The oil filter makes sure the oil circulating through the engine is of good quality. Frequent oil changes are an important step in routine maintenance, because it rids the engine of the old oil by replacing it with new, fresh oil (NAPAFilters). An…

The first source was a bathtub faucet which was measured in a closed bathroom. It was measured about six inches from the faucet only getting 75.7dBA. The second source was an all metal toolbox closing. Measured six inches from the source, while it is only a quick increase at 90.1Dba, everyday exposure can be damaging. The next source was an acoustic guitar being strummed in my apartment. The meter was roughly one foot away on a table. This was under the minimum requirement to be considered…

According to the House Energy and Commerce Committee, the chemicals used in fracking fluids include over 750 different chemicals. Some are innocuouse (salt, gelatin) while others pose significant human health hazards (methanol, isopropanol and 2-butoxyethanol). About 650 of the 750 chemicals used in fracking operations are known carcinogens, according to the report filed with the U.S. House of Representatives in April 2011. They include toxic chemicals like benzene and tholuene. Returning…

The organic care hand wash had 2cm worth of inhibition zone, dettol hand wash had 1cm, palmolive had 0.9cm and dettol santisier had 0.8cm. In terms of which one was the most ocst efficient, dettol hand wash cost $2.00, while organic care costs $4.00. The hypothesis was refuted, as it was said the popularity of the product would dictate its effectiveness and efficiency, yet the most popular product is dettol. Dettol is seen in everywhere, on hygiene posters, tv ads, in public bathrooms etc., and…
