Answer:

Maximum and mean velocity will be equal i.e 0.5 m/s

Explanation:

given data:

viscosity = 0.001 m^2/s

Thickness of thin film = 2 mm = 0.002 m

Neglecting the body weight hence no shear stress

Mean velocity is given V

[tex]V = \frac{\nu}{D}[/tex]

[tex]V = \frac{0.001}{2*10^{-3}}[/tex]

V = 0.5 m/s

Maximum and mean velocity will be equal i.e 0.5 m/s
