Heat transfer rate per unit area is called_________________?
Correct answer: B. Heat flux
- A. Thermal conductivity
- B. Heat flux
- C. Heat transfer co-efficient
- D. Thermal diffusivity
Explanation
Heat flux is the heat-transfer rate per unit area, q/A, and is commonly measured in W/m². Thermal conductivity is a material property, while the heat-transfer coefficient relates flux to a temperature difference.
