Match LIST-I with LIST-II and select the correct answer using the codes given below the lists.\[\begin{array}{|c|c|} \hline \textbf{LIST-I} & \textbf{LIST-II} \\ \hline \text{A. Stanton number} & \text{I. Natural convection for ideal gases} \\ \hline \text{B. Grashof number} & \text{II. Mass Transfer} \\ \hline \text{C. Peclet number} & \text{III. Forced convection} \\ \hline \text{D. Schmidt number} & \text{IV. Forced convection for small Prandtl number} \\ \hline \end{array}\] Choose the most appropriate answer from the options given below:

Answer 1

Step 1: Define Nusselt number in forced convection. In forced convection, the Nusselt number (Nu) measures the heat transfer augmentation from convection relative to conduction. It depends on the Reynolds number (Re), which indicates the flow regime (laminar or turbulent), and the Prandtl number (Pr), which describes the fluid's thermal properties.

Step 2: Evaluate the provided options. - (A) The Nusselt number in forced convection is a function of both the Reynolds number (Re) and the Prandtl number (Pr). - (B) The Grashof number (Gr) is associated with natural convection, not forced convection. - (C) The Prandtl number (Pr) and Grashof number (Gr) are relevant to natural convection. - (D) The Schmidt number (Sc) pertains to mass transfer, not directly to heat transfer in forced convection.

Final Answer: \[ \boxed{\text{Re and Pr}} \]
