Athin film of oil (v=0.001 m^2/s) 2mmthick flows down to
a surface inclined at 30 degrees to thehorizontal. what is the
maximum and mean velocity offlow?

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

V = 0.5 m/s

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