Extracted text: 5. Two immiscible fluids of equal density are flowing down a surface inclined at a 30° angle. The two fluid layers are of equal thickness h = 2.5 mm; the kinematic viscosity of the upper fluid is twice that of the lower fluid, which is viower=2×10“ m² s'. Find the velocity at the interface and the velocity at the free surface. Plot the velocity distribution.
