Is copper or aluminum a better heat conductor?
Copper is a better heat conductor compared to aluminum. Copper has higher thermal conductivity, meaning it can transfer heat more efficiently than aluminum. This is why copper is commonly used in applications that require high heat transfer, such as heat exchangers and cookware.
Is copper a bad heat conductor?
No, copper is actually a very good heat conductor. It is commonly used in applications where efficient heat transfer is required, such as in electrical wiring and heat exchangers.
What is the answer to the analogy fiberglass is to insulation as conduction is to what?
The answer is "heat transfer." Fiberglass is commonly used as insulation to reduce heat transfer, while conduction is a form of heat transfer where heat is transferred through a material.
Does aluminum or copper conduct the most heat?
Copper conducts heat better than aluminum. This is because copper has a higher thermal conductivity, meaning it can transfer heat more effectively. Copper is commonly used in cooking pots and pans due to its excellent heat conduction properties.
What metal conducts more heat iron or copper?
Copper conducts heat better than iron. This is because copper has a higher thermal conductivity, allowing it to transfer heat more efficiently. This property makes copper a preferred choice in various industries where heat conduction is essential.
What is the heat transfer coefficient for copper in SI units?
400W/mK
What is Overall Heat transfer coefficient?
The overall heat transfer coefficient represents the rate at which heat is transferred between two mediums per unit area and per unit temperature difference. It combines the individual resistances to heat transfer in conduction, convection, and radiation into a single value. A higher overall heat transfer coefficient indicates a more efficient heat transfer process.
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 convective heat transfer coefficient of water and how does it impact the rate of heat transfer in a system?
The convective heat transfer coefficient of water is a measure of how easily heat can move through water. A higher convective heat transfer coefficient means heat can transfer more quickly. In a system, a higher convective heat transfer coefficient can increase the rate of heat transfer, making the system more efficient at exchanging heat.
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)."
How does the resestance to heat transfer of the matrrial of the condenser pipe effect on the transfer coefficient?
The resistance to heat transfer of the material of the condenser pipe affects the overall heat transfer coefficient by increasing the overall thermal resistance. A higher resistance to heat transfer in the material of the condenser pipe will reduce the heat transfer coefficient, making heat transfer less effective. This can result in reduced efficiency in the condenser's operation.
What is the heat transfer coefficient of water and how does it affect the efficiency of heat transfer processes?
The heat transfer coefficient of water is a measure of how well water can transfer heat. It is influenced by factors such as temperature, flow rate, and surface area. A higher heat transfer coefficient means that heat can be transferred more efficiently between water and another substance. This is important in heat transfer processes like cooling systems or heating systems, where efficient heat transfer is crucial for optimal performance.
What is the convective heat transfer coefficient of water and how does it affect heat transfer processes?
The convective heat transfer coefficient of water is a measure of how easily heat can transfer through water by convection. It represents the rate at which heat is transferred between a solid surface and water through the movement of fluid particles. A higher convective heat transfer coefficient means that heat can transfer more efficiently, leading to faster heat exchange processes. This coefficient is influenced by factors such as temperature, flow rate, and surface area, and plays a crucial role in various heat transfer applications, such as cooling systems and thermal management.

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 formula to calculate the natural convection heat transfer coefficient in a given system?
The formula to calculate the natural convection heat transfer coefficient in a system is h k Gr(1/4) / L, where h is the heat transfer coefficient, k is the thermal conductivity of the fluid, Gr is the Grashof number, and L is the characteristic length of the system.
Is copper or aluminum a better heat conductor?
Copper is a better heat conductor compared to aluminum. Copper has higher thermal conductivity, meaning it can transfer heat more efficiently than aluminum. This is why copper is commonly used in applications that require high heat transfer, such as heat exchangers and cookware.
