Consider steady, incompressible, and fully developed laminar flow of a viscous liquid down an incline with no pressure gradient. the velocity profile was derived in example 5.9. calculate the kinematic viscosity of the liquid if the film thickness on a 30o slope is 0.8 mm and the maximum velocity is 15.7 mm/s

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)
