Definition

quotient of heat flow rate and area:

q = \frac{\dot{Q}}{A}

where $\dot{Q}$ is heat flow rate (heat flow rate) and $A$ is area (ISO 80000-3: Space and time) of a given surface

quotient du flux thermique par l'aire:

q = \frac{\dot{Q}}{A}

où $\dot{Q}$ est le flux thermique (heat flow rate) et $A$ est l'aire (ISO 80000-3: Space and time) d'une surface donnée
