Water is flowing continuously from a tap having an internal diameter 8 × 10 –3 m. The water velocity as it leaves the tap is 0.4 ms –1 . The diameter of the water stream at a distance 2 × 10 –1 m below the tap is close to:
Text Solution
Verified by ExpertsThe correct answer is:
D
Diameter = 8 × 10 –3 m
v = 0.4 m/s
v = 
= 
= 2 m/s
A 1 v 1 = A 2 v 2
π 
= π × 
d = 3.6 × 10 –3 m.
