Consider streamline flow of a liquid flowing through a tube as shown in the figure which of the following is correct regarding velcities of liquid at different points ?

A

`v_(1)= " constant " , v_(2)= " constant " , v_(3)= " constant " `

B

`v_(1) ne v_(2) ne v_(3)`

C

`v_(1)=v_(2)=v_(3)`

D

Both (a) and (b) current

Text Solution

Verified by Experts

The correct Answer is:
D
In the streamline flow
`V_(1)`= constant, `V_(2)`=constant, `V_(3)`=constant
`V_(1) ne V_(2) ne V_(3)`
