What else can I help you with?
If the oxygen partial pressure in your mix is 1.3 ata at a depth of 37 msw (122 fsw) what is the fraction of oxygen in the mix?
0.28
Reduction of oxygen which forms water occurs during?
The reduction of oxygen that forms water occurs during respiration. It occurs when oxygen and hydrogen mix to form what is called metabolic water.
What kind of reaction is responsible for the liberation of Carbon dioxide in red blood cells?
respiration- The body takes in oxygen and glucose and turns it into carbon dioxide. Glucose is a mix of Carbon D, oxygen, and water. The body uses the oxygen, gets rid of the carbon dioxide and uses some of the water( the rest of the water is waste).
What does oxygen do for fire?
Fire is the release of heat and light during the very rapid combination of oxygen with another substance that we call the fuel of the fire. Although there are other oxidizers that can perform a similar function, in most cases in everyday life you cannot have a fire without a source of oxygen.
What is rust and how does it form?
Rust forms when metals containing iron mix with the oxygen in the air or the water and create a compound named iron oxide. This compoumd has water molecules, so we call it a hydrated compound. Chemically and very simply speaking, iron atoms lose a few electrons to oxygen atoms. This process, where electrons are lost from atoms, is the oxidation process. When oxidation occurs it produces a chemical reaction that creates iron oxide
What is the gas for welding?
Oxygen and acetylene for flame welding. Argon for Tig welding CO2 for MIG welding steels Argon for MIG welding aluminum TRI-mix for robotic mig of steels. And helium is added for some overhead welding.
How do you put acetylene in a sentence with at least 10 words?
Oxy-acetylene burners produce a very hot flame, that will melt metal.
Which compressed gases are used for welding?
Some common compressed gases used for welding include acetylene, argon, carbon dioxide, and helium. These gases are often used in various combinations depending on the welding process and materials being joined.
Explain oxy- acetylene welding process?
Oxygen and acetylene tanks feed into your torch. When opened, the gases will mix in a chamber in the torch, then flow out of the torch tip. Using a spark lighter, they will ignite causing a flame. This flame can be adjusted to a neutral flame by moving the knobs on the tank regulators.
How does oxygen and acetylene help pump a car tire?
Not a good idea. That is an extremely explosive mix.
What is the procedure of oxy acetylene?
The oxy-acetylene welding process involves using a torch to mix oxygen and acetylene gases in a controlled manner to generate a high-temperature flame. The flame is then directed onto the metal workpiece to melt it, while a filler rod can be added if necessary to create a weld joint. Proper safety measures, such as wearing protective gear and ensuring proper ventilation, should be followed when using oxy-acetylene equipment.
Can you mix helium and acetylene?
It is not recommended to mix helium and acetylene as they have different physical and chemical properties. Helium is an inert gas while acetylene is a flammable gas. Mixing them could create a hazardous situation due to the risk of combustion or explosion.
Which gases are used in normal welding process?
Depends on what you think of as normal welding. Gas welding use oxygen-acetylene. MIG/TIG use Argon. MAG, use an argon-something mix. Depending on what materials you are welding, there are some more options tha might be used.
What does oxygen have to do with welding?
Oxygen is an atmospheric gas that is unwanted in almost all welding processes because in it's molten state, metal oxidizes very easily and causes a weak joint. Weld surfaces are protected during the welding process to keep oxygen from contaminating the weld either by a shielding gas, flux, or in torch welding, the torches own exhaust. Occasionally however, oxygen may be added to the shielding gas mix in small amounts to stabilize the arc and reduce undercutting.
What color is a acetylene hose?
Acetylene hoses are typically color-coded with a red cover to indicate that they are specifically designed for use with acetylene gas. The red color helps to prevent mix-ups with other gas hoses and ensures proper safety precautions are followed.
What are the properties and applications of an argon oxygen mix?
An argon oxygen mix is a gas combination that is commonly used in welding and cutting applications. It provides a stable and controlled environment for these processes, allowing for precise and efficient results. The properties of an argon oxygen mix include its ability to improve the stability of the welding arc, enhance the penetration of the weld, and reduce the formation of oxides on the metal surface. Overall, this gas mixture is valued for its versatility and effectiveness in various metalworking applications.
What is the colour of oxygen cylinder in welding?
It is usually green, but owner-bottles (those not owned and rented out by a welding company) can be any color. There should always be a label on all cylinders identifying the contents. Never go just by color.
