Q. If a river has a discharge of 500 cubic meters per second and the cross-sectional area of the river is 100 square meters, what is the velocity of the river?
A.
2 m/s
B.
5 m/s
C.
10 m/s
D.
20 m/s
Solution
Velocity = Discharge / Area = 500 m³/s / 100 m² = 5 m/s.
Q. If a river has a sediment transport capacity of 200 kg/m³ and flows at a rate of 10 m³/s, what is the total sediment transported in one hour? (2000)
A.
72000 kg
B.
60000 kg
C.
360000 kg
D.
120000 kg
Solution
Total sediment = Sediment capacity × Flow rate × Time = 200 kg/m³ × 10 m³/s × 3600 s = 7200000 kg.
Q. If a river is 300 meters wide and the current flows at 2 m/s, how long will it take a swimmer to cross the river if he swims at a speed of 1 m/s perpendicular to the current?
A.
300 seconds
B.
150 seconds
C.
200 seconds
D.
100 seconds
Solution
Time to cross = Width / Speed across = 300 m / 1 m/s = 300 seconds.
Q. If a river's width increases from 50 meters to 100 meters while maintaining the same depth of 3 meters, what is the change in cross-sectional area? (2022)
A.
150 m²
B.
200 m²
C.
300 m²
D.
400 m²
Solution
Initial area = 50 m × 3 m = 150 m²; Final area = 100 m × 3 m = 300 m²; Change = 300 m² - 150 m² = 150 m².
Q. If a school awards a total of $1200 in scholarships, and the first place receives $600, the second place receives $300, and the third place receives $200, how much is left for the fourth place? (2023)
A.
$100
B.
$200
C.
$300
D.
$400
Solution
Total awarded = 600 + 300 + 200 = 1100. Amount left for fourth place = 1200 - 1100 = $100.
