The flow rate of a liquid through a 2.0 cm radius pipe is 0.008 m3 /s. the average fluid velocity in the pipe is:

The average fluid velocity in the pipe can be obtained by dividing the flow rate of the liquid by the cross-sectional area of the pipe.

Av velocity = Flow rate/Cross-sectional area

Given, flow rate of the liquid = 0.008 m³/s

Cross-sectional area = , radius of the pipe is 0.02 m.

Substituting the values we get,

Av velocity=

= 6.36 m/s

Average velocity of the fluid is 6.36 m/s.
