What is disc utilization?
Disk utilization is the amount of data present on your storage drive. A certain data uses a part of the available space on the storage drive. Disc utilization is the same as disk utilization. -------------------------------------------------------------------------------------------------------------- It can refer to the amount of space being used on a disk or how busy the disk is with respect to I/O operations.
What is a cog wheel?
A simplistic answer is: A cog wheel is a circular disc that has teeth round the edge. These teeth usually mesh with the teeth of another cog. If one cog is turned, the other cog moves too. The cogs can be made from metal or plastic.
Which tool is used to correct internal 'hi-low' when preparing a 4-in. steel pipe for welding?
The tool used to correct internal hi-low when preparing a 4-in. steel pipe for welding is a four-inch grinder with cutting disc.
What are cbn grinding wheels made of?
The wheels are generally made from a matrix of coarse particles pressed and bonded together to form a solid, circular shape. Various profiles and cross sections are available depending on the intended usage for the wheel. They may also be made from a solid steel or aluminium disc with particles bonded to the surface.
What are 5 safety precautions needed when setting up an abrasive cutting wheel to cut steel?
There are many precautions to take when cutting with any tools, here are a few: 1. Ensure that the cutting disc is correctly fitted and that any protective guards are in place. In the UK, the equipment may need to be electrically PAT tested. (Portable Appliance Testing). 2. Wear the correct Personal Protective Equipment (PPE). Goggles, Gloves, Ear defenders etc. 3. Ensure that the steel is securely fixed and will not move during cutting. 4. Create a safe working area. Screens/barriers and warning signs may be required if other people are nearby. 5. Remove any flammable items from the area (Oily rags, fuel cans, paper etc). Sparks can cause fires. A fire-extinguisher should be on standby and possibly a fire-watcher.
Why you keep condenser rupture disc in steam turbine?
You want the rupture disk located at the LP exhust side of the steam turbine. This is placed here to prevent over pressure of the condencer in case loss of vacuum occurs. It is not placed in the condencer because the condencer is not rated for pressure.
What is purpose of rapture disc in steam turbine?
when increase the turbine pressure it s add to the rapture disc and it s will be broken and reduce the pressure.
Where is the rupture disc located on a low pressure chiller?
the rupture disc is piped off the chiller barrel (evaporator) and will vent the refrigerant outside incase of over pressure of the unit
Where is the rupture disc located on a low pressure chiller picture?
The rupture disc on a low pressure chiller is typically located on the refrigerant circuit close to the compressor. It is designed to release pressure in the event of an overpressure situation to prevent damage to the system. The exact location can vary depending on the chiller's design and manufacturer.
How does a rupture disk differ from a fusible plug?
A rupture disk (disc) is a pressure relief device that reliefs pressure when the pressure inside the protected equipment exceeds the set pressure. A fusible plug reliefs pressure when the plug is weakened due to high temperature.
A rupture disc on a recovery vessel for low pressure refrigerants relieves at what psi?
A rupture disc on a recovery vessel for low pressure refrigerants typically relieves at a pressure range of around 15 to 25 psi, depending on the specific design and safety requirements of the vessel. This low pressure setting is essential to ensure safe operation and prevent overpressure conditions that could lead to vessel failure. Always refer to the manufacturer's specifications for the exact relief pressure for a particular vessel.
What is rupture disc leak tightness?
For standard type rupture disc devices the leak tightness is typically 1 x 10-3 mbar.l/sec He or better, when applying O-ring seals between the rupture disc and its holder (if approved by the manufacturer!) then 1 x 10-6 mbar.l/sec is achievable. Higher leak rates will require welded type rupture discs where 1 x 10-8 mbar/le/sec or better will be feasable.
Describe a herniated vertebral disc due to whiplash injury?
A herniated disc occurs when the outer layer of the disc is damaged, the disc may rupture and the gel-like interior leak, putting pressure on adjacent nerve roots causing tingling, numbness or burning.
What are other names for a herniated disc?
A herniated disc is also referred to as a slipped, rupture, bulging, or protruding disc.
Where should the discharge from a rupture disc be piped for venting on a low pressure chiller?
The discharge from a rupture disc on a low-pressure chiller should be piped to a safe location away from personnel and equipment, typically to a designated vent stack or exhaust system. It is essential to ensure that the discharge point is elevated and directed away from any occupied areas to prevent exposure to potentially hazardous materials. Additionally, the venting system should comply with local regulations and safety standards to manage any released substances effectively.
How rupture disc fitted in steam condenser?
A rupture disc is mounted between two pipe flanges, one mounted to the condenser the other either unmounted or mounted to a vent pipe.
What is a herniatic disc?
As the spinal disc becomes less elastic, it can rupture. When the disc ruptures, a portion of the spinal disc pushes outside its normal boundary--this is called a herniated disc.
