Thermal diffusivity sheet metals.
Thermal diffusivity calculator thermal diffusivity is a material property which describes the rate at which heat flows through a material typically measured in mm s or in hr.

Calculate overall heat transfer coefficient.
In heat transfer analysis the ratio of the thermal conductivity to the specific heat capacity at constant pressure is an important property termed the thermal diffusivity the thermal diffusivity appears in the transient heat conduction analysis and in the heat equation.
This property is commonly used in conjunction with other thermodynamic properties to estimate the cooling time of molten plastic in the injection molding process.
In other words it is the measure of thermal.
It measures the rate of transfer of heat of a material from the hot end to the cold end.
Thermal conductivity k is the quantity of heat transmitted due to an unit temperature gradient in unit time under steady conditions in a direction normal to a surface of the unit area.
It represents how fast heat diffuses through a material and has units m 2 s.
In heat transfer analysis thermal diffusivity is the thermal conductivity divided by density and specific heat capacity at constant pressure it measures the rate of transfer of heat of a material from the hot side to the cold side.
It has the si derived unit of m s thermal diffusivity is usually denoted α but a h κ k and d are also used.
Calculate conductive heat transfer.
In heat transfer analysis thermal diffusivity is the thermal conductivity divided by density and specific heat capacity at constant pressure.
