Question 375: Properties of Matter

Question

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?

Accepted Answer

According to BernoulliÃ¢ÂÂs theorem,
$$P + {1 \over 2}\rho {v^2}$$ = constant and Av = constant
If A is minimum, v is maximum, P is minimum.

Answer

The velocity is maximum at the narrowest part of the pipe and pressure is maximum at the widest part of the pipe.

Answer

Velocity and pressure both are maximum at the narrowest part of the pipe.

Answer

velocity and pressure both are maximum at the widest part of the pipe.

Answer

The velocity is minimum at the narrowest part of the pipe and the pressure is minimum at the widest part of the pipe.
