What room temperature is copper?
You can put copper in any room you like, and it will be able to match the temperature of the room through a normal heat transfer process, just like any other material.
Is copper a bad heat conductor?
No. Copper is a good conductor of heat.
The copper is an insulator?
yes copper is actually a very good insulator to both heat and electric conducting A2: NO. Copper is about the second-best electrical conductor, next to silver. It is also a very Good heat conductor. Try heating an iron poker in a fire. The heat travels slowly to the opposite end. A copper wire, however, if stuck in the fire, will transfer heat Very quickly--you won't be able to hold the other end of it! wikipedia.org/copper
What happens if you heat copper?
If you heat copper it will oxidise and therefore lose electrons.
Do kitchen pots made from different materials transfer heat at different rates?
Yes. But there are two different qualities of heat transfer. When you talk about the rate of heat transfer, you may be talking about the speed the pot changes temperature or how well it spreads heat. The rate of temperature change is called thermal diffusivity. A copper pot would change temperature about 1.3X faster than an aluminum pot, and 10X faster than an iron pot. How well it spreads the heat is called thermal conductivity. A copper pot would spread the heat about 2X better than an aluminum pot and about 8X better than an iron pot. This is assuming the thickness of each pot is the same. The ability of heat to pass through the pot, is also thermal conductivity. For some things you'd want a pot that transfers heat evenly and quickly, copper. For other things you'd want a pot that holds the heat, iron.
What is the heat transfer coefficient for copper in SI units?
400W/mK
Why is a car radiator made of aluminum?
The purpose of a radiator is to transfer heat from the engine to the atmosphere, so radiators need to be made of a material with a high heat transfer coefficient. Aluminum has a high heat transfer coefficient. In other words, aluminum conducts heat very well. There are other materials, such as copper, which conduct even better, but aluminum is more economical to use than copper.
What is the value of an overall heat transfer coefficient in an engine oil cooler?
I have a book (Introduction to heat transfer - Bergmann), there is an example of an oil cooler cooled by air (crossflow heat exchanger with both fluids unmixed). There is written: "... with an overall heat transfer coefficient of 53 W/(m²*K)."
Conductive heat transfer coefficient of ptfe?
12
Does juice temperature increase with increasing convective heat transfer coefficient at any constant kettle surface temperature?
Yes, the juice temperature increases with an increasing convective heat transfer coefficient at any constant kettle surface temperature. The convective heat transfer coefficient represents the efficiency of heat transfer from the kettle to the juice. As the convective heat transfer coefficient rises, more heat is transferred from the kettle surface to the juice per unit of time. This increased efficiency results in a faster temperature rise in the juice. Therefore, a higher convective heat transfer coefficient enhances the overall heating process, leading to a greater temperature increase in the juice even when the kettle surface temperature remains constant.
What is the Heat transfer coefficient for aluminiun oxide?
around 40 W/mK
Why saturated steam is used in exchangers frequently rather then superheated?
The heat transfer coefficient of superheated steam is poor. Saturated steam has a better heat transfer coefficient, and also most of the heat transferred from steam occurs because of the condensation phase change.
What is the value of convective heat transfer coefficient of water having steel imerged?
What is the heat transfer coefficient os carbon steel
Why does heat move by conduction in an empty space?
If you are asking about a box filled with a gas, then heat transfer can modeled as conduction through a solid. The requirement would have to be no fluid flow (obviously there is movement at the micro level), and the conductive heat transfer coefficient would be very low.Convection heat transfer is dependent on that conductive heat transfer coefficient of the liquid and is based on something called the Nusselt number.If you are asking about heat transfer through a completely void space, then heat would travel by means of radiation.
What is the heat transfer coefficient of fiberglass boat hull?
I think it is arounf 9w/m2k
High heat transfer coefficient film-wise condensation or drop-wise?
In dropwise condensation about 5-8 times higher coefficient than filmwise.
What materials heat up faster?
Materials that heat-up faster are known as conductors. Silver, Copper, Gold and Aluminium are some conductors that have the ability to transfer heat.
