Question

Water flows through
varying cross-section. Its spee
points where
What will be the speed of flow a
ows through a horizontal pipe of
-section. Its speed is 5.20 m/s at
ats where cross-sectional area is 4.20 cm
the speed of flow at points where
Toss-sectional area is 7.00 cm??
1.04 m/s
2.08 m/s
(3)
3.12 m/s
(4)
4.16 m/s​

Answer 1

Answer:

using continuity equation

A1V1=A2V2

A1=4.20

V1=5.20

A=7

V2=A1V1/V2=4.20*5.20/7=0.6*5.20

V2=3.120m/s

option 3 is right
