Question

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:

• A. A - II, B - I, C - III, D - IV
• B. A - I, B - I, C - IV, D - II
• C. A - III, B - I, C - II, D - I
• D. A - II, B - III, C - IV, D - I

Hint:

When matching dimensionless quantities, remember their applications in fluid dynamics and heat transfer processes.

Answer 1

The Correct Option is A

Step 1: Understand the dimensionless quantities.
- **Stanton number (A)** is related to **Mass Transfer** (II). - **Grashof number (B)** is used for **Natural convection for ideal gases** (I). - **Peclet number (C)** is related to **Forced convection** (III). - **Schmidt number (D)** is used in **Forced convection for small Prandtl number** (IV).

Final Answer: \[ \boxed{A - II, B - I, C - III, D - IV} \]
