This formula uses 5 Variables
Variables Used
Thermal Conductivity - (Measured in Watt per Meter per K) - Thermal Conductivity is the rate at which heat passes through a specified material, expressed as the amount of heat that flows per unit time through a unit area with a temperature gradient of one degree per unit distance.
Heat Flow Rate - (Measured in Watt) - Heat Flow Rate is the amount of heat that is transferred per unit of time in some material, usually measured in watt. Heat is the flow of thermal energy driven by thermal non-equilibrium.
Thickness of Sample - (Measured in Meter) - Thickness of Sample is the measure of the distance between two surfaces of an sample, usually the smallest of three dimensions.
Sample Area - (Measured in Square Meter) - Sample Area is defined as the space occupied by the surface of a sample.
Change in Temperature - (Measured in Kelvin) - The Change in Temperature is the difference between the initial and final temperature.
