Water flows through a frictionless duct ...

Water flows through a frictionless duct with a cross-section varying as shown in fig. Pressure `p` at points along the axis is represented by

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
A
`AV =` const.
`P (1)/(2) rhov^(2) =` constt
If velocity increases then pressure decreases.
