Question

Water is flowing with a velocity 4m/s in a cylinder of diameter 8cm. It is connected to a pipe with its end
tip of diameter 2cm. Velocity of water at the free end is:
A) 64 m/s
B) 96m/s
C) 32m/s
D) 4."m/s
E)9m/s​

Answer 1

Answer:

64 m/s

Explanation:

A₁V₁=A₂V₂

4 × (π×(4×10^-2)²) = V₂× (π× (1×10^-2)²)

∵area =πr²

v₂= 64m/s
