A fluid is in streamline flow across a horizontal pipe of variable area of cross section. For this which of the following statements is correct?
Options
- AThe velocity is maximum at the narrowed part of the pipe and pressure is a maximum at the widest part of the pipe.
- BVelocity and pressure both are maximum at the narrowest part of the pipe.
- CVelocity and pressure both are maximum at the widest part of the pipe
- DThe velocity is minimum at the narrowest part of the pipe and the pressure is minimum at the widest part of the pipe.
Correct answer
A. The velocity is maximum at the narrowed part of the pipe and pressure is a maximum at the widest part of the pipe.
Step-by-step solution
The velocity is maximum at the narrows part of the pipe and pressure is maximum at the widest part of the pipe.
(Using equation of continuity constant.)
