Answer» Correct Answer - Option 4 : 50,000 m3 Given: Length of pipe = 2 m Breadth of pipe = 10 m Speed of water = 10 km/hr Time = 15 minutes Calculation: Speed = 10 km/hr = 10 × (5/18) m/sec = 25/9 m/s Time = 15 minutes = (15 × 60) sec = 900 sec Length (H) = (25/9) × 900 = 2500 Volume = L × B × H = 2 × 10 × 2500 = 50,000 m3 ∴ Volume of water collected in 15 minutes is 50,000 m3. |
