Question

Match List I with List II:

List I (Dimensionless Quantity)	List II (Application)
(A) Number of transfer units	(I) Recuperative type heat exchangers
(B) Periodic flow heat	(II) Regenerative type heat exchangers
(C) Chemical additive	(III) A measure of heat exchanger size
(D) Deposition heat exchanger	(IV) Prolongs dropwise condensation surface
	(V) Fouling factor

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

Hint:

Match each term in List I with its corresponding application in List II by understanding their roles in heat exchangers. For example, NTU measures efficiency, and fouling is related to deposition.

Answer 1

The Correct Option is C

To solve the given question, match the items in List I with their appropriate applications in List II based on their definitions and usage in heat exchanger systems.

Matching:

1. (A) Number of transfer units
   It represents the effectiveness of a heat exchanger, commonly used in Recuperative type heat exchangers.
   Match: (I)
2. (B) Periodic flow heat
   Periodic flow heat applies to systems where heat storage occurs, typical of Regenerative type heat exchangers.
   Match: (II)
3. (C) Chemical additive
   These are used to modify surface properties, often to Prolong dropwise condensation surfaces.
   Match: (IV)
4. (D) Deposition heat exchanger
   Deposition involves fouling effects, which are addressed using the Fouling factor.
   Match: (V)

Final Answer:

(A)-(I), (B)-(II), (C)-(IV), (D)-(V)

Correct Option: 3. (A)-(I), (B)-(II), (C)-(IV), (D)-(V)
