Why does heat transfer differ from thermodynamics?
it incorporates the rate and the modes of heat transfer
Thermodynamics
it is the study of the end state of a process during which heat interaction occurs, while disregarding the rate or the mode of the heat transfer processes
Conduction
the heat transfer that will occur across two stationary mediums
Convection
the transfer of heat by the actual movement of a fluid
Radiation
heat transfer that occurs via electromagnetic waves, requires no medium
Why is heat transfer important?
it allows for the design and sizing of devices in which heat transfer takes place
Thermal diffusivity
how much energy a material stores per unit volume
Thermal conductivity
how well a material conducts heat
Total heat flux
