A fluid flows through a horizontal pipe having two different cross-sections of area

A

and

2A

. If the pressure at the thin cross-section is

p

and fluid velocity is

v

, the velocity and pressure at the thicker cross-section is (take the density of fluid as

\rho

)

View answer and explanation

Correct option: C

\frac{v}{2},p + \frac{3}{8}\rho {v^2}

Option C (v/2, p + (3/8)ρv²) is correct because it applies both the continuity equation and Bernoulli's principle correctly.
