Q.6
ICAR AIEEA PG 2024 - Agricultural Engineering and Technology (Q.104)
MCQ (Single Correct)
1 cm of rainfall over a catchment area of 1 \(\text{km}^2\) represents a volume of water equal to:
1 \(\text{km}^2\) के जलग्रहण क्षेत्र (catchment area) पर 1 cm वर्षा जल की कितनी मात्रा (आयतन) को दर्शाती है?

Calculation of rainfall volume:
Rainfall depth \(d = 1\text{ cm} = 0.01\text{ m} = 10^{-2}\text{ m}\). Catchment area \(A = 1\text{ km}^2 = (1000\text{ m})^2 = 10^6\text{ m}^2\).
Volume of water \(V = A \times d = 10^6\text{ m}^2 \times 10^{-2}\text{ m} = 10^4\text{ m}^3\) (or 1 hectare-meter = 10,000 \(\text{m}^3\)).

Thus, the volume of water is \(10^4\text{ m}^3\).

गणना:
वर्षा की गहराई \(d = 1\) सेमी \(= 0.01\) मीटर \(= 10^{-2}\) मीटर
जलग्रहण क्षेत्र \(A = 1\text{ km}^2 = 10^6\text{ m}^2\)
जल का कुल आयतन \(V = A \times d = 10^6\text{ m}^2 \times 10^{-2}\text{ m} = 10^4\text{ m}^3\) (अर्थात 10,000 घन मीटर)।
