Given : Water ideally flows through a pipe of radius of 6 cm at a rate of 5m/s. the pipe then narrows to a radius of 2 cm.
To Find : what is the new velocity of the water
Solution:
Water ideally flows through a pipe of radius of 6 cm at a rate of 5m/s.
Cross-section area = πr² = π(6)² = 36π cm²
velocity = 5 m/s
pipe then narrows to a radius of 2 cm.
Cross-section area = πr² = π(2)² = 4π cm²
new velocity = V m/s
Cross-section area * velocity = Constant
=> 4π * V = 36π * 5
=> V = 45
new velocity of the water = 45 m/s
