Q1: The velocity distribution of viscous fluid through a circular/pipe is :

ANS:C - parabolic

The velocity distribution of a viscous fluid flowing through a circular pipe is typically parabolic. This velocity distribution arises from the balance between the pressure gradient and the viscous forces acting on the fluid within the pipe. As the fluid moves away from the walls of the pipe, the velocity increases due to the pressure gradient and decreases toward the walls due to the no-slip condition, resulting in a parabolic velocity profile. Therefore, the correct option is parabolic.
