Detailed Solution
Download Solution PDFGiven:
Depth of river (d) = 20 m
Width of river (w) = 36 m
Flow rate = 2.7 km/hr
Time = 1 minute
1 km/hr = 1000 m / 60 min
Formula used:
Volume of water = Depth × Width × Flow rate × Time
Calculation:
Flow rate (in m/min) = 2.7 × 1000 / 60
⇒ Flow rate = 45 m/min
Volume of water = 20 × 36 × 45 × 1
⇒ Volume = 32400 m3
∴ The correct answer is option (4).
