Fluid

oobleck. Non-newtonian fluids have incredibly interesting properties. The act of punching a non-newtonian fluid such as cornstarch in water will surprise you greatly. The force of your hand will make the atoms rearrange in the solution which results in the fluid to behave like a solid. When the fluid behaves like a solid, your hand will not go through. Whereas, if you place your hand in slowly, it will go through profitably. Slime is classified as a non-Newtonian fluid because it…

For many investigators, evidence that is considered “probative” for collection and evaluation is: biological (blood, body fluids, hair), latent print (finger and foot prints), footwear, tire tracks, trace evidence (fibers/soil), digital (cell phone records or internet logs), tools, drugs, and firearms (NFSTC 1). The kind of evidence that the investigator collects will always…

Hydraulic fracturing, also known as fracking, is the process of drilling and injecting fluid into the earth’s surface at high pressures in order to fracture the clastic sedimentary rock or shale rock surface. Fracturing the shale rock releases the natural gas, petroleum, or water that could be trapped inside these underground natural reservoirs. The wells are drilled vertically into the earth’s surface for hundreds or thousands of feet and include horizontal or directional extensions to allow…

Frack Off Marissa and Derek Smith and their kids from Pennsylvania cannot live a healthy life any longer. There are ten Hydraulic Fracking wells on their property; one in particular is hundred feet away from their home. From the fracking wells in nearly spitting distance of Marissa’s home, her family is getting sick and they are no longer able to swim, fish or play in the streams near their house. Five generations of their family have lived in the same house and swam, fished and played in the…

2). And using the Labstix strip to test urine sample for blood, ketone, glucose, and protein. Three different kinds of drinks were used: water, Coke, and Gatorade because we are trying to study the kidneys by osmotic regulation in maintaining the fluid balance in the body and analyze the result we get from the experiment. Also, to compare the changes in urine flow rate, specific density, and urine pH of an adult human during fasting and…

The heat exchanger has main application in thermal power plant and engines. A shell and tube heat exchanger has two concentric tubes the inner tube contains the hot fluid whereas the outer tube has cold fluid flowing in it. The heat exchange takes place from hot fluid to cold fluid and this heat exchange is governed mainly by conduction. As we know, Q=UA ∆T For the parallel flow heat exchanger shown the heat transfer is given by, dq= -m_h c_h dT_h= m_c c_c dT_c The…

LBin2to Nm2. The way to find velocity was previously stated. The equation for finding or mass flow rate is as follows: mass of waterflow time, the mass of water was calculated from the 10 fluid ounces that were used in the most successful launch. The flow time was constant for all rockets tested at 0.5 seconds. The fluid ounces had to be converted to metric units as well, then were converted into units of mass. The Fgis found by taking the mass of the rocket multiplied by acceleration, in…

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…

Initial Resuscitation: The principle approach to managing a patient with sepsis is to perform vigorous fluid resuscitation. As stated previously severe sepsis occurs when the patient exhibits signs of widespread tissue hypoperfusion (i.e. having elevated blood lactate concentration, sepsis-induced hypotension or oliguria). Therefore, aiming to correct such…

Archimedes was a mathematician, physicist, astronomer, engineer and inventor. Archimedes was the first big mathematician, as well as consider the best mathematician of that era. Archimedes was born in the Greek city-state of Syracuse. His father, Phidias, was an astronomer. The fact that his father was an astronomer made him motivated to do all the inventions he did. He was really close to King Hieron and his son, Gelon. He worked for them, when he lived in Alexandria. He invented the sciences…
