Heat transfer rate or flux (given thermal conductivity, temperature difference and distance)
Formula description
Heat transfer is a discipline of thermal engineering that concerns the exchange of thermal energy from one physical system to another. Heat transfer is classified into various mechanisms, such as heat conduction, convection, thermal radiation, and phase-change transfer. All forms of heat transfer may occur in some systems.
