If you solve this question for the laminar case the maximum velocity will be 2*uavg, 2*uavg, this means chaotic system dissipate more energy due to viscous effect. And can be related to the natural phenomenon as big eddies that form in the fluid consumes energy in form of angular velocity or vorticity and get converted to smaller eddies and eventually die out dissipating energy to the environment.

Max. Velocity = 2 Avg. Velocity --> For Pipe.
Max. Velocity = 1.5 Avg. Velocity --> For Plate.
Max. Velocity = 1.5 Avg. Velocity --> For Plate.

Boss maximum velocity is 0.97 and avg velocity is 0.81 then how become its ratio 2?

Vavg = 1/8myu.dp/dx.R^2.
Vmax= 1/4myu.dp/dx.R^2.
Vmax= 1/4myu.dp/dx.R^2.

In laminar flow, the maximum velocity is 2 times the average velocity.

Please can you describe the answer?

Umax = -1/4u (Something which writing difficult).
And Uavg.= -1/8u.
And Uavg.= -1/8u.
