(a)as shown in figure (a)
(b)as shown in figure (b)
(c)as shown in figure (c)
(d)as shown in figure (d)
Attempt This Question
Not attemptedCorrect Answer: (d) as shown in figure (d)
For fully developed laminar (streamlined) flow in a circular pipe, viscous drag makes the velocity zero at the walls and maximum along the axis, producing a parabolic velocity profile (figure d in the paper). Hence option (d) is correct. ([licchavilyceum.com](https://licchavilyceum.com/upsc-civil-services-prelims-1996-solved-question-paper/))
