8.9 An incompressible viscous liquid flows steadily down an incline due to gravity. The flow is laminar and the velocity profile derived in Example 5.9, is

where θ is the slope of the incline and h is the thickness of the film. The fluid kinematic viscosity is 1 × 104 m2/s, the slope is 30 , and the film thickness is 0.8 mm. Determine the maximum velocity and the flow rate per meter of width.
