An incompressible fluid flows steadily through a cylindrical pipe which has radius 2 R at point A and radius R at point B farther along the flow direction. If the velocity at point A is v, its velocity at point B is

An incompressible fluid flows steadily through a cylindrical pipe which has radius 2R at point A and radius R at point B. Further, along the flow direction, if the velocity at point A is v, its velocity at point B will be

An incompressible fluid flows steadily through a cylinder pipe which has radius 2 R at point A and radius R at point B further along the flow direction. IF the velocity at point A is v, its velocity at a point B will be
