Identify the incorrect statement from the following options:

Explanation

Option A correctly describes natural convection as fluid movement due to buoyant forces from density changes. Option B accurately defines the Stanton number as Nusselt number divided by Reynolds number times Prandtl number. Option C correctly states that the Peclet number quantifies the ratio of convective to conductive energy transport. However, option D is incorrect because the Colburn jH factor is actually given by the Stanton number multiplied by the cube root of the Prandtl number, not simply the product of the Stanton and Prandtl numbers.
