What is the definition of piping class?
Pipe class is a collection of most compatible components considering dimensional and material properties for the intended service over a range on pressure and temperature specified.
Which of the material is used for the swamping resistance that is connected in series with the working coil of a voltmeter?
A swamping resistor is usually manufactured from the metal alloy manganin (trade name), or other alloy with similar resistance/temperature characteristics -i.e. practically zero temperature coefficient of resistance. In other words, its resistance will remain more-or-less constant over a wide range of temperature variation.
What is the temperature range of low temperature carbon steel in which range of operating temperature it can be used?
Carbon Steel is used upto 427 oC or upto 1100 oF.
What is working temperature of EN24 with heat treatment material?
EN24, also known as 4340 steel, typically has a working temperature range up to about 300°C (572°F) after appropriate heat treatment. The heat treatment process, which often includes quenching and tempering, enhances its mechanical properties, allowing it to maintain strength and toughness at elevated temperatures. However, specific applications may demand different temperature limits based on design and environmental conditions. Always consult material specifications and engineering guidelines for precise applications.
What is the temperature class PU?
As per API 6A temperature classification, -20 deg F to 250 deg F operating temperature range.
Name the phenomenon that occurs when a etal is loded well witin the elastic range at a temperatue of 800 degrees andit slowly deforms permanently?
The phenomenon you are describing is known as creep. Creep is the slow, time-dependent deformation of a material under a constant load or stress, typically occurring at elevated temperatures. In this case, the material is being loaded within its elastic range but still deforms permanently due to the prolonged exposure to high temperature.
What is plateau temperature?
Plateau temperature is the temperature range in a phase transition at which a material remains stable despite changes in temperature. It is often observed in materials like polymers and can be an important property in various applications like material processing and design. At the plateau temperature, the material undergoes structural changes without a significant rise in temperature.
Application of pour point?
At a defined temperature a liquid become semisolid and doesn't easily flow: this is the pour point. This is important to establish the temperature range in which this material can be used.
What is the material used in RTD?
The most common materials used for RTD (resistance temperature detector) sensors are platinum, nickel, and copper. Platinum is the most commonly used material due to its high accuracy and stability in a wide temperature range.
What is the phenomenon called that occurs when a metal is loaded well within the elastic range at a temperature of 800F and it slowly deforms permanently is?
The phenomenon you're describing is known as "creep." Creep occurs when a material, such as metal, undergoes slow and permanent deformation over time when subjected to a constant load or stress, particularly at elevated temperatures like 800°F. This behavior is significant in applications where materials are exposed to high temperatures and stress over extended periods, leading to potential failure if not properly accounted for in design.
How do you find a temperature range?
The highest temperature minus the lowest temperature is the temperature range. The temperature range is how many degrees is in between the highest and lowest temperatures.
What is a mass movement that occurs when underlying material is weakened and can no longer support material on top of it?
A mass movement that occurs when underlying material is weakened and can no longer support material on top of it is called a landslide. This can be triggered by factors such as heavy rainfall, earthquakes, or human activities that destabilize the slope. The movement can range from slow, gradual processes like creep to rapid events like rockslides or mudslides.
What material would allow the thermometer to measure the largest range of temperature?
A thermocouple would allow the thermometer to measure the largest range of temperature, as it can measure from extremely low temperatures to very high temperatures. Thermocouples are made of two different metals that generate a voltage proportional to the temperature difference between the hot and cold junctions.
How do you calculate the range in temperature?
To calculate the range in temperature, subtract the lowest temperature from the highest temperature in the data set. This will give you the spread of temperatures from the lowest to the highest in the range.
If a sidewalk is 3 feet wide and 184 feet long how many expansion joints are needed?
The answer will depend on what material the sidewalk is made from and the maximum range in temperature.
What property of mercury make it good material for thermometer?
It's a liquid over a fair range of temperatures and it expands and contracts noticeably with small changes in temperature.
If temperature increases than the resistance increase or decreases?
If temperature increases the resistance will also increase. This is why a light bulb is a non ohmic conductor. As the light bulb filament gets hotter its resistance will increase.Additional CommentsIt depends upon the material involved. In general, for pure metal conductors an increase in temperature will cause their resistance to increase. For insulators, an increase in temperature will cause their resistance to decrease -which is why excessive temperature is often the main reason why insulation fails. Alloys can be manufactured that will maintain a relatively constant resistance over a wide range of temperatures.Temperature affects resistance indirectly. What is actually being affected is the material's resistivity. Resistivity is one of the factors that determines resistance.The resistance of any given material can be calculated over wide range of temperatures, using the temperature coefficient of resistance for that material.
