Abstract: This lab is envisioned to experimentally authenticate the theoretic formulations leading hydrostatic force and pressure middle on flooded flat superficial. The impartial of this laboratory is to regulate the hydrostatic insertion interim on plane superficial engrossed in water when the surface is partially submerged or fully submerged. Also to determine the untried center of pressure and the theoretic center of pressure for every of the trials executed. Introduction: When the quadrant is

3.4. Swelling behavior The swelling behavior of the DCMC crosslinked gelatin-PEG composite hydrogel fibers is studied and presented in Fig. 3. It shows that the equilibrium swelling ratio of the hydrogel fibers is very high, which is found to be between 89 and 93%. The result indicates that the hydrogel fibers are effective biomaterials for using as wound dressings since they can absorb wound exudates and provide moist environment for wound leading to acceleration of wound healing. The water in hydrogel

Bernoulli’s theorem is a special application of the laws of motion and energy. The principle equation describes the pressure measured at any point in a fluid, which can be a gas or a liquid, to the density and the velocity of the specified flow. The theorem can be explained by the means of imagining a particle in a cylindrical pipe. If the pressure on both sides of the particle in the pipe is equal, the particle will be stationary and in equilibrium. By implementing the second law of motion the

TIVA may be favoured as the anesthetic technique of choice for the following reasons ADVANTAGES OF TIVA: 1. Rapid smooth induction and maintenance of anesthesia Induction of anesthesia with propofol is smooth and associated with a low incidence of excitatory side effects. Doses of 1 to 2.5 mg/kg (depending on patient age, physical status, and use of premedicant drugs) induce anesthesia in approximately 30 seconds. The speed of onset and the dose of propofol needed for induction are dependent on the

Should I Major in Nursing Science or not? Nursing is hard job. Nurses who work hard by taking care of the patient. I am in college with no career choice. I had no experience about what it will be like to be a nurse. My mom always wanted me to be an accountant. So I decided to major in accounting. Accounting is all about numbers. And I was good at math in high school. I was enjoying math, and never got bored when I was doing my homework. However, I like to study about human body structures. Taking

Resistance) The force opposite to the force of the motion of an object through a fluid. (Fluid in this report refers to the medium the bird/object is moving through- i.e. Air). Drag is created because the object and the fluid are exchanging momentum upon impact, and thus creating a force opposite to the motion of the object. Equation for drag: Fd = 1/2(Cd * A * ρ * v2) FD: Drag Force Cd: Drag Constant A: Area ρ: Density of Fluid v: Flow Velocity relative to Object Instrument to measure Drag: Force Balance

BS1003 – Organic Chemistry Practical 1 Laboratory Report Name: Tristan Chan Yew Kit, U1640436J (T8) Effects of Dichloromethane(DCM) in Extraction of Caffeine from Tea Leaves Purpose To investigate the ability for Dichloromethane(DCM), a moderately polar organic solvent, to extract aqueous caffeine molecules, originating from Tea Leaves suspended in water. Introduction Caffeine, defined chemically as 1,3,7-trimethylxanthine (C8H10N4O2), is an alkaloid that can be found in tea leaves, coffee and many

grown.Being an automotive technician, also known as a mechanic, requires technical problem-solving skills. What exactly are the requirements needed to be an automotive technician? What are some of the main responsibilities that a technician must fulfill? What benefits does a career as an automotive technician provide? A high school diploma or a GED is typically necessary to become an auto technician. Although employers would prefer mechanics with a technical school degree in Automotive Technology

Automotive technicians often work indoors that are usually noisy and very dusty. The downfall of being a mechanic is that it has a high risk of injury than most other jobs. But that didn 't stop me. My first assignment as to change tires. It did not go well, I accidentally punctured a tire instead of changing it, it was a terrible day for

about “703,800 people currently working as Automotive Service Technicians and Mechanics in the United States” (“How Many People Are Currently Employed as Automotive Service Technicians and Mechanics in the United States?”). There are “283,315 mechanic businesses in the United States alone” (“Industry Market Research, Reports, and Statistics”). Future mechanics would want to know information about: what being a mechanic or automotive service technician entails, whether it be the definition of the

It Like Magnus). To kick the soccer ball farther than normal, the ball needs to be pumped up harder than most other soccer balls (Live-strong). Magnus effect is the force exerted on a fast spinning cylinder or sphere moving through air or another fluid in a direction at an angle to the axis of spin (Magnus Effect/Physics). “The ball is like a rock in a fast flowing river — the water splits around the rock, then swirls to fill in behind the rock, causing turbulence” (Bend It Like Magnus). Turbulence

Do you know how to fix a dent? The average American doesn't. If a person is looking to go into a career that is fun and very fruitful then, that person should become an auto body technician. Body techs repair cars that have been damaged by collision. Auto body techs get to work miracles on clients' beloved cars. An auto body technician is a vital part of the automotive industry. These skilled professionals interact with clients to repair, restore, or refinish vehicles. To begin, Auto body technicians

“centripetal” force. Pursuing his hypothesis Newton proved as a theory and then published his observations in ‘Philosophiae, Natrualis, Principia Mathematica’(A comprehensive account of his theory of gravitation and mechanics) Continuing his extensive work in the field of mechanics, Newton expanded the scope of gravitational force eventually developing the theory three laws of motion. The prevalent theory has cause a ripple in perspective of understanding physics. Although there were plagiarism

Isaac Newton was born in Woolsthorpe, Lincolnshire, in 1642 and died in London in 1727. The English physicist and mathematician earlier in his career decided to devote himself to the reading of the Treaties of philosophy, natural science and mathematics of the most important thinkers and scientists of the time. From 1684 to 1686 he devoted himself to the writing of the work "Philosophiae Naturalis Principia Mathematica", better known as "Principia," which was published in 1687 In 1671, it was welcomed

is this supersonic shock wave that is important to ramjet air intake functioning, and it was the cause of major headaches in the design of ramjets that would work reliably. It is important to remember that the air molecules in this wave are moving at the speed of sound, and no faster. The simplest air intake design is just a hollow tube with a circular opening - a pipe. Imagine a pipe fastened to a supersonic airplane or rocket. When the pipe is propelled through the air at supersonic speeds the

injection thrust vectoring nozzles are another advanced design that allow pitch and yaw control from un-gimbaled nozzles. India's PSLV calls its design "Secondary Injection Thrust Vector Control System"; strontium perchlorate is injected through various fluid paths in the nozzle to achieve the desired control. Some ICBMs and boosters, such as the Titan IIIC and Minuteman II, use similar designs. 1.4 Materials used: In order to withstand the higher temperatures of exhaust gases, the nozzle must be manufactured

Flying in the Theatre A system of ropes, pulleys and counterweights is used in a theatre in order to lift scenery, flats and sometimes people among other theatre hardware. This system is commonly known as a fly system or a rigging system. Flying people can be a dangerous act and must be carried out by a competent person with adequate training and experience. A fly system consists of battens, lines (made of both hemp and wire), blocks, a cradle and counterweights. When flying people a harness is also

2.3 Aerofoil Aerofoil is the cross-sectional of an object that are moved through a fluid such as air, and aerodynamics force created. Aerofoils are employed on aircraft as wings so then it will produce lift or others depending to the blade shape to produce thrust. The two of these forces are perpendicular to the air flow. Drag is a consequence of the production of lift/thrust and acts parallel to the airflow. Other aerofoil surface includes tail-planes, fins, winglets, and helicopter rotor blades
