Question

In the case of motion of a fluid in a tube where area of cross-section is maximum,
a) velocity is maximum
b) pressure is maximum
c) velocity is minimum
d) pressure is minimum

• A. b, c are correct
• B. a, d are correct
• C. a, b are correct
• D. c, d are correct

Answer 1

The correct option is A b, c are correct

By the equation of continuity,
$AV$ = constant
where, $A$ is area and $V$ is velocity. If area is maximum, velocity would be minimum.
By the Bernoulli's equation,
$P+\frac{1}{2}\rho V^2+\rho gh$ = constant
If velocity is minimum, the pressure would be maximum.
