### Right Answer is: Thermal conductivity to the equivalent thickness of the film of fluid

#### SOLUTION

Film coefficient or heat transfer coefficient (h) is defined as the ratio of thermal conductivity of the material to the equivalent thickness of the film.

h = (Thermal conductivity)/(Equivalent thickness of film)

Its unit is W/m2K.
