Along a streamline,

A

The velocity of a fluid particle remains constant

B

The velocity of all fluid particles crossing a given position is constant

C

The velocity of all fluid particles at a given instant is constant

D

The speed of a fluid particle remains constant

Text Solution

Verified by Experts

The correct Answer is:
B
As we know for a streamline flow of a liquid velocity of each particle at a particular cross-section is constant, because Av = constant (law of continuity) between two cross-section of a tube of flow.

The figure shows a non-viscous, incompressible and steady flow in front of a sphere. A-B is a horizontal streamline. It is known that the fluid velocity along this streamline is given by V=V_(0)(1+(R^(3))/(x^(3))).V_(0) is velocity of flow on this streamline when xrarr(-oo) . It is given that pressure at xrarr(-oo) is P_(0) and density of liquid is rho . (i) Write the variation of pressure along the streamline from pointA, far away from the sphere, to point B on the spehre. (ii) Plot the variation of pressure along the streamline from x=-oo to x=-R.
