Properties of Matter question

2013 · Q156

NEETPhysicsProperties of MatterMCQ+4 / −1
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?
  1. A
    The velocity is maximum at the narrowest part of the pipe and pressure is maximum at the widest part of the pipe.
  2. B
    Velocity and pressure both are maximum at the narrowest part of the pipe.
  3. C
    velocity and pressure both are maximum at the widest part of the pipe.
  4. D
    The 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

According to Bernoulli’s theorem,

P+12ρv2P + {1 \over 2}\rho {v^2}P+21​ρv2 = constant and Av = constant

If A is minimum, v is maximum, P is minimum.
