WebFeb 1, 2024 · The quantity of heat transmitted per unit area per unit time to or from a surface is referred to as heat flux. It is a derived quantity since it is based on the idea of two quantities: the amount of heat transfer per unit time and the region to or from which the heat transfer takes place. The joule per second or watt is the SI unit of heat rate.
