How does cryogenic machining work?
Cryogenic machining means cooling down the cutting tool with liquid carbon dioxide or nitrogen to very low temperatures ( -78,5°C or -109,3°F and below). This enables a clean production process without conventional cutting fluid that is hazardous to both the environment and to health.
What is cryogenic deflashing?
Cryogenic deflashing is a form of deflashing used to remove any excess plastic from parts that are molded. As molds wear and age they develop places where flash can occur. Typical areas for flash are along the part including parting lines and edges. Flash can be removed using various deflashing methods. Cryogenic deflashing utilizes batch processing to remove flash from parts. If thousands of parts are molded at a time and exhibit flash, then they can be processed quite quickly. Parts are processed in a cryogenic deflashing machine that lowers temperatures and shoots media. The lower temperatures allow the flash to freeze and become heavy. Then media is shot at the parts which takes off the flash. Normal cycles are less than 30 minutes. Cryogenic deflashing offers repeatable results again and again. The surface of the parts are not destroyed or discolored. The only thing that is removed is the flash. Cryogenic deflashing is great for rubber, silicone, various plastics, and some metals. It is also is a cheaper process due to its speed of execution and lot sizes. I have been working with cryogenic deflashing equipment for several years and I can say that they are one of the most cost-effective ways to deflash any part.
Why cryogenic fluid is superior to any other cooling fluid in powered equipments?
due to the high heat generation in powered equipments there is requirement of maintaining the properties of fluid at high temperature hence cryogenic material have better properties.
What means RAFT in blast furnace?
It is Raceway Adiabatic Flame Temperature present in the front of tuyears.
Why is a cryogenic engine important?
A cryogenic engine is important because it will carry heavy payloads to geosynchronous transfer orbit. This is highly essential for future telecommunication and space exploration. It is able to carry up to five tons compared to the 1.5-ton payload capacity of PSLVs.
Is melting process is adiabatic process?
An adiabatic process in the opposite of a diabatic process. The adiabatic process occurs without the exchange of heat with its environment. A diabatic process exchanges heat with the environment.
How does entropy change in an adiabatic process?
In an adiabatic process, entropy remains constant.
What is the difference between an isentropic process and an adiabatic process in thermodynamics?
In thermodynamics, an isentropic process is a reversible and adiabatic process, meaning there is no heat exchange with the surroundings. An adiabatic process, on the other hand, does not necessarily have to be reversible, but it also involves no heat exchange with the surroundings.
What is an adiabatic process?
An adiabatic process is one in which there is no heat transfer into or out of the system. This means that any change in internal energy of the system is solely due to work done on or by the system. Adiabatic processes are often rapid and can lead to changes in temperature and pressure without heat exchange.
What is an adiabatic process and how is it defined as one in which there is no heat exchange with the surroundings?
An adiabatic process is when there is no heat exchange with the surroundings. This means that no heat is added or removed from the system during the process.
What is another name for riversible adiabatic process?
Another name for a reversible adiabatic process is an isentropic process. This type of process involves no heat exchange with the surroundings and is characterized by constant entropy.
What are the key differences between an adiabatic and isothermal graph in thermodynamics?
In thermodynamics, the key difference between an adiabatic and isothermal graph is how heat is transferred. In an adiabatic process, there is no heat exchange with the surroundings, while in an isothermal process, the temperature remains constant throughout the process.
A change in temperature without an accompanying change in the amount of heat present is called what?
It is called adiabatic or an adiabatic process.
What is ratio of reversible adiabatic process?

What is adiabatic proccess?
An adiabatic process is one in which there is no transfer of heat between a system and its surroundings. This means that the change in internal energy of the system is solely due to work done on or by the system. Adiabatic processes are often characterized by a change in temperature without any heat exchange.
What is the relationship between the work done in an adiabatic process and the change in internal energy of a system?
In an adiabatic process, the work done is equal to the change in internal energy of a system.
What are the characteristics and implications of a reversible adiabatic process?
A reversible adiabatic process is a thermodynamic process that occurs without any heat exchange with the surroundings and can be reversed without any energy loss. This process is efficient and ideal for theoretical calculations. The implications of a reversible adiabatic process include the conservation of energy and the ability to achieve maximum work output.
