Identify the incorrect statement from the following options:

Explanation

Option A is correct because drying a solid above the critical moisture content indeed involves two degrees of freedom. Option B is accurate as Sherwood and Nusselt numbers, as well as Schmidt and Prandtl numbers, are analogous in mass and heat transfer respectively. Option D correctly describes the common practice of positioning hot gases based on pressure in shell-and-tube heat exchangers. However, option C is incorrect since forced convection is generally more effective in increasing mass transfer rates when the Schmidt number is lower, not higher.
