• A. 2.64
• B. 4.13
• C. 6.77
• D. 5.62

Answer 1

The correct option is B 4.13

Rabi

$Q_{rabi}=\frac{A{d}_w}{t}=\frac{4000\times {10}^4\times 16\times {10}^{-2}}{4\times 7\times 24\times 60\times 60}=2.64Cumec$

Kharif

$Q_{kharif}=\frac{A.d_w}{t}=\frac{2500\times {10}^4\times 20\times {10}^{-2}}{2\times 7\times 24\times 60\times 60}=4.13Cumec$

Greater value = 4.13 cumec
