ICAR AIEEA PG 2024 - Agronomy (Q.73)

MCQ (Single Correct) +4 −1

One cumec-day is equal to :

एक क्यूमेक-दिन (Cumec-day) किसके बराबर होता है?

8.64 ha-cm 8.64 ha-cm 8.64 ha-m 8.64 ha-m Correct 12.64 ha-m 12.64 ha-m 12.64 ha-cm 12.64 ha-cm

Conversion calculation:

$1\text{ cumec} = 1\text{ m}^3/\text{sec}$
$1\text{ day} = 24 \times 60 \times 60 = 86,400\text{ seconds}$
Total volume in $1\text{ cumec-day} = 1 \times 86,400 = 86,400\text{ m}^3$
Since $1\text{ hectare} = 10,000\text{ m}^2$, $1\text{ ha-m} = 10,000\text{ m}^3$

\[ \text{Volume in ha-m} = \frac{86,400\text{ m}^3}{10,000\text{ m}^3/\text{ha-m}} = 8.64\text{ ha-m} \]

Thus, $1\text{ cumec-day} = 8.64\text{ ha-m}$ (or $864\text{ ha-cm}$).

परिकलन:

$1\text{ क्यूमेक} = 1\text{ m}^3/\text{सेकंड}$
$1\text{ दिन} = 86,400\text{ सेकंड}$
क्यूमेक-दिन में कुल आयतन $= 86,400\text{ m}^3$
$1\text{ हेक्टेयर-मीटर (ha-m)} = 10,000\text{ m}^3$

\[ \text{आयतन (ha-m)} = \frac{86,400}{10,000} = 8.64\text{ ha-m} \]

अतः विकल्प 2 सही है।
