Airbags are safety features that are designed to save passengers from harm in a head-on collision. Airbags react within milliseconds of a crash, and the folded nylon bag quickly becomes inflated with nitrogen gas. The inflated airbag has the role of being a cushion for passengers and prevents them from hitting into the steering column and dashboard, which can cause painful injuries for passengers. Airbags were invented by John Hetrick in 1953 after Hetrick, his wife and young daughter got

to measure the material in the gas phase and to see how the ideal gas experiment could apply to the physical. In this the material we used was, a sip-lock plastic bag, a large plastic beaker, thermometry, dry ice, water, and butane lighter. Introduction In this lab, the experiment focused on the relationship between the temperature and pressure of an ideal gas that was dry ice inside the closed container. Therefore, the volume remains constant because the ideal gas was in a closed container. Experiment

Theory 3 Mass Flow rate analysis 4 Exhaust Gas 6 Results 7 Conclusion 8 Reference 9 Equivalent ratio of a gas turbine Introduction and Procedure For this experiment, a two shaft gas turbine (ET792) was used. At the core of ET792 are a so-called gas generator and a free-running power turbine. The gas generator consists of a radial compressor, a combustion chamber and a radial turbine. The compressor and turbine are mounted on a shaft. The gas turbine works as an open cyclic process, with

What makes the ball curve: Soccer players can make the ball curve by applying a Force, kicking, to the ball that is not in the center of the ball itself. When the ball is struck on the side by a player the ball spins while it is moving forward. In the case of the picture below, the soccer ball was struck on the right side of the ball and is spinning counter-clockwise. What causes the ball to actually curve in the air is a difference in the pressures on either side of the soccer ball. On the left

Boil erm…Boyle’s Law Some of the earliest quantitative measurements were performed on gases. Robert Boyle conducted one early study in 1662. Robert Boyle used a J-shaped piece of glass tubing that was sealed on one end. A gas was trapped in the sealed end of the tube and unstable amounts of mercury were added to the J-shaped tube to vary the pressure of the system. Boyle scientifically varied the pressure and measured the volume of the gas. These measurements were performed using a fixed

lts and Discussion The heart of a laboratory report is the presentation of the results and the discussion of those results. In some formats, "Results" and "Discussion" appear as separate sections. However, P.B. Medawar [1979] makes a strong case that the two should appear together, particularly when you have many results to present (otherwise, the audience is faced with a "dump" of information that is impossible to synthesize). Much here depends upon your experiment and the purpose of your laboratory

Hydrostatic vs Osmotic Pressure Hydrostatic pressure is the pressure going outward from the capillary. Hydrostatic Pressure forces the fluid from capillary to move outward into the interstitial space. Osmotic pressure is the water trying to move from interstitial space into the capillary Hydrostatic pressure will be greater in the arterial side as opposed to the venule side. Osmotic Pressure is constant throughout the capillary. Because the hydrostatic pressure drops across the capillary
