A drainage canal discharges 0.2 m3/sec of water from 250 hectares area, the drainage coefficient of the land will be

🔑 Key Points
[Drainage Co-efficient (D.C)]:
→ The depth of water drained off from a given area in 24 hours is called the drainage co-efficient. It can also be defined as the design capacity of the drainage system and is typically expressed as the depth of water removed in 24 hours.

📌 Important Points
→ Formula:
D.C = (Total water discharge in 24 hrs (m³)) / (Total land area in sq. meters)
→ Calculation:
D.C = 0.2 × 24 × 60 × 60 / (250 × 10000)
D.C = 6.912 × 10⁻³ m = 6.912 mm

📝 Additional Information
→ Therefore, the drainage coefficient of the land will be 7 mm.
