Question

Match List-I with List-II

List-I (Formula)	List-II (Purpose)
(A) Kennedy	(I) Open channel flow
(B) Chezy	(II) Friction factor
(C) Darcy-Weisbach	(III) Design of open channels
(D) Manning's	(IV) Estimates on seepage loss in canal systems

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

Hint:

To quickly solve this:
- Darcy-Weisbach is synonymous with pipe friction and the friction factor (C \(\rightarrow\) II).
- Manning's equation is the standard for the design of open channels (D \(\rightarrow\) III).
- Chezy's is the classic open channel flow equation (B \(\rightarrow\) I).
These three matches immediately point to Option 4.

Answer 1

The Correct Option is D
