Question:-
The maximum velocity of a one-dimensional incompressible fully developed viscous flow, between two fixed parallel plates, is 6ms-1.
The mean velocity (in ms-1) of the flow is
Option (A)
2
Option (B)
3
Option(C)
4
Option(D)
5
Correct Option:
(C)
Question Solution:
For fully developed viscous flow between two fixed parallel plates, the ratio (Vmax / Vavg) is given by (Vmax / Vavg) = (3/2) Þ Vavg = (2/3). Vmax = (2/3).6 = 4m/s
