Question

Velocity has to be the same at the same horizontal level in case of steady laminar flow.

(a) True

(b) False

Answer 1

Right choice is (b) False

For explanation I would say: Velocity can be different at the same horizontal level if the area of the cross section at the two points is different.                                                                                                                                                       This is according to the equation of continuity, A1v1 = A2v2, where A is area and v is velocity.
