• A. A, B and C Only
• B. A, C and E Only
• C. B, D and E Only
• D. B, C and D Only

Hint:

Important formulas and facts: \[ \boxed{ C_d = C_c \times C_v } \] \[ \boxed{ \text{Water sheet over weir} = \text{Nappe} } \] \[ \boxed{ \text{V-notch} \Rightarrow \text{Small discharge measurement} } \]

Answer 1

The Correct Option is B
