A liquid film of constant thickness 1 mm flows down an inclined plane as shown in the figure below. The velocity profile for this flow is given as, V = 2ay(h-y/2) m/s, where h is the thickness of the film. If the dynamic viscosity and density of the fluid are 950 cP and 1261 kg/m respectively, find the volume flow rate per unit width in mm/s. The acceleration due to gravity may be taken as 9.81 m/s.
