Heat Flow Rate in Conduction Formulas

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. And is denoted by Q. Heat Flow Rate is usually measured using the Watt for Power. Note that the value of Heat Flow Rate is always negative.
