It depends on the medium of heat transfer. For solids, it is conduction heat transfer. For liquids and gases, it is convection heat transfer. for vacuum (no medium), it is radiation heat transfer.

What is overall surface efficiency of fins?
it is ratio of the total heat transfer from the surface area associated with both the fins and exposed portion of the base to maximum heat transfer from same surface area (in ideal conditions we get maximum heat transfer)
How steam heat is lost in a plant?
steam is lost in the plant through variuos way. But generally it is through heat transfer to the product to be heated by the steam. Also heat transfer through the conducting passage.
Function of heat transfer oil in industry?

What role does the sun have on how heat is transferred?
Due to nuclear reaction in the sun it emits enormous heat ,and heat does not require any medium to transfer.
Which is the fastest mode of transfer of heat?
radiation, of course.
Which method of heat transfer is fastest conduction convection or radiation?
Conduction . . . depends on the properties of the material through which the heat is conductedConvection . . . depends on the physical movement of the material carrying the heat from level to levelRadiation . . . electromagnetic waves, moving from place to place at the speed of light.Looks like Radiation would transfer heat the fastest.
What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.
Why transfer of heat in fluids take place by convection?
Heat transfer will use all three modes, but convection is (by far) the fastest, thus you can ignore the other two if you wish. This will produce errors in your calculations - you must decide if the errors are small enough to be acceptable.
What are two examples of heat transfer?
Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.
What device typically has the fastest transfer rate?
RAM (Random Access Memory) storage devices typically has the fastest transfer rate.
How does temperature affect the rate of heat transfer?
For conductive and convective heat transfer, the rate of heat transfer is proportional to the the temperature difference; if you double the difference you will double the rate of heat transfer. For radiative heat transfer, the rate of heat transfer is proportional to the difference of the 4th powers of the absolute temperatures.
What is convective heat?
Convection heat transfer is the transfer of heat by the movement of a fluid.
The transfer of heat by fluid?
The transfer of heat by fluid is convection.
What do conduction and convection have in common?
They're both modes of heat transfer via material media.
Winds transfer heat energy by what method of heat transfer?
convection
How heat transfer is controlled?
There is a special mechanism that controls heat transfer.
