Fuel For A Paintball Marker
The Reason that people need a tank when they play paintball is because you need a way to force the paintballs out of the gun and this cannot be achieved effectively by just using a spring. What they decided to do was to fuel the paintballs by pushing them with a gas. The way in which they did this was to put the gases, either Oxygen, Carbon Dioxide or Nitrogen under extreme pressure until they turned into a liquid and once they are in a liquid form they can be blown into a tank which probably looks something like this.
Carbon Dioxide must be under a pressure of at least 415.8 kPaA For it to turn into liquid form. Oxygen and Nitrogen are very similar to this.
The way in which the gas is let out is that there is a needle in a valve in the top of the tank and when the tank is screwed into the paintball marker the needle gets pressed down and the entire system becomes pressurized and is ready to be fired. Then when the gun is cocked and the trigger is pulled the bolt is pushed forward, accelerated by the force of the C02 acting behind it and pushes the paintball out. Then the bolt comes back into the read position and the C02 is no longer flowing and is again pushing against the bolt.
There are some problems with this system however. One of the major ones is called snowing, where liquid C02 actually gets into the paintball marker, this is not good for multiple reasons, first of all having the liquid C02 on the moving parts inside a marker is not good for it, since many of the parts inside are rubber or plastic. The second problem with this is since the gas is in liquid form it is not expanding as fast and there for is not pushing the paintballs as effectively. This causes a white snow like substance to come out of the barrel of the marker. There are several way that this problem is dealt with, some markers have the guns stored in a vertical position to keep the liquid in the bottom of the tanks. Other markers employ gas lines or expansion chambers, these are basically just tubes or cylinders that run from the tank to the marker and give the C02 a chance to turn from a liquid to a gas.
There are many internal parts to the injector. Starts with a barrel then moves down to a plunger then there is a check valve, below that is a spacer with the nozzle springs inside of it, lastly is the nozzle. All of these parts have specific and unique jobs. Nozzle has a needle in it that works kind of like a piston that once the pressure build up the needle forces forward and sprays fuel. There is a spacer above the nozzle with the nozzle springs that force the needle down. Above the spacer is a check valve, the check valve allows the right amount of fuel into the nozzle. The plunger and barrel are located above the check valve. It has a spring on the plunger that has to hold resistance of the pressure until it reaches the correct amount before it will let the injector fires. There is two internal o-rings one that is around the plunger and one that sets between the nut and body.
CO2 is not very reactive at normal temperatures, but it does form carbonic acid, (H2CO3 ) in aqueous solution. This will undergo the typical reactions of a weak acid to form salts. I call it carbonic acid because in the presence of moisture, which we have all around us, it will make an acid. CO2 is also responsible for the acidic pH of rain water. So that nasty stuff called “acid rain” is caused by CO2. A solid hydrate CO28H20 separates from aqueous solutions of CO2 that are colder at elevated pressures. It is very stable at normal temperatures, but forms CO and O2 when heated above 1700oC.
The first known paintball gun or “marker” was made by John Barker in 1982. At the time he had a job designing air guns for Daisy Inc. The gun that he made was a single shot pump gun; he called it the “splatmatic”. Daisy did not want to market his gun so he started a small company with some of his friends and called it Splat Markers. The company was soon a success and in 1986 he changed the name to JT Products. Now JT Products is one of the largest paintball companies in the world, producing practically everything needed and used in the game of paintball. They have also made the NPA (National Paintball Association). This was created in 2002 and has many different teams that are sponsored by a variety of companies. Paintball has come a long way since the creation of the splatmatic and is now a very popular and sport.
Soldiers were ordered to load and they would take a cartridge and rip it open. Sometimes they would open them with their own teeth. After they opened it, they poured powder into the pan of the firing mechanism to fill it up. They would pour the main portion of the powder down into the barrel, and then they folded paper and put it into the barrel and dropped the ball at the top. They used the ramrod under the barrel of the musket to...

There are a few different physics engines that programmers use now for their games. There are 2 main physics engines that programmers use: Havok, and Math Engine.
When the ECU sends a pulse to the injector, which closes the electrical circuit, the injector’s solenoid creates a magnetic field. This magnetic field attracts the needle’s magnet opening the exit orifice and letting flow the fuel.
...e can be used to practice tactical strategy like clearing rooms, laying mine, and sweeping areas. The squad has used a laser system like laser tag but because the lazer’s do not cause an impact there's not any adrenaline but with the paintball guns the impact causes adrenaline and is more relative with the adrenaline to the battlefield (Military Combat Training with Spyder Paintball Markers).
Soccer is a sport that’s very challenging and during the course of this semester I’ve found physics can also be described as challenging. As far as I was concerned soccer and physics were both challenging and that was all they had in common, consequently upon researching them both this semester I found that I was wrong. For me this was nothing new because I’ve found that physics isn’t a subject that can be skimmed, but rather it has to be studied to the finest detail. Those small details if missed can make all your efforts worthless. Or on the positive side understanding those details can make your efforts worth it in the end. And in soccer if you understand the physics, which to most players would be considered as the small details, it pays off in the end. So really how does physics come into play with soccer?
Physics is a part of everyday life. It is evident in the modern technological devices we use in every day experiences and objects around us. Although physics is understood to be only useful in the classroom, physics can also be applied to one the most popular activities on the planet, basketball. Whether jumping for the ball, or leaping for a slam dunk, the human body follows the same laws of projectile motion as do other objects. The sport that includes shooting, passing, running, and dribbling involves topics covered in physics such as force, friction, effects of air resistance, velocity, air pressure and energy. Basketball also involves factors such as projectile motion in making a basket, gravity and its effects on passing and dribbling, and Newton’s First and Third Law on passing and a number of others.
There are many aspects to the game of basketball and physics can be applied to all of them. Although to be good at basketball it is not necessary to play it from a physics point of view. Basketball players become good by developing muscle memory for the actions that must be performed in the game of basketball from years of practice. Nevertheless knowing some of the physics in the game of basketball can help a good player be a better player. In this paper I will cover the three most important aspects of the game, shooting, dribbling and passing.
The Browning M2 .50 caliber machine gun is better known as the 'Ma Duce' to those who have had the pleasure of firing this heavy barrel machine gun. In 1919 John M. Browning developed the M2 .50 cal as an anti-aircraft weapon. The M2 was first introduced into the United States Military in 1933 and is used by many militaries through out the world today. Since 1933 there have been little changes made to this weapon system. The BMG (Browning Machine Gun) is a crew served, belt fed, air-cooled, recoil operated machine gun capable of firing in single shot or fully automatic.
Carbon dioxide is commonly found as a gas and is never a liquid. It sublimes to a solid known as 'dry ice' which is used as a substitute for normal ice as it is a lot colder and doesn't melt.
M253 Cannon (barrel): The M253 cannon consists of the barrel, sealed at the lower end with a removable breech plug that houses a removable firing pin. At the muzzle end is a cone-shaped Blast Attenuator Device (BAD) that is fitted to reduce noise.
"Pump slowly we get a lot of petrol. Pump with speed, get a little," claimed Project Manager of Muslim Consumers Association of Malaysia (PPIM), Noor Nirwandy Mat Noordin. The quantity of petrol is a bit different although the digit display shows that petrol pumped is one liter due to the entry with the air. In order to prevent the entry of air into the fuel tank, it is better to fill the petrol slowly.
