Complete answer
Extracted text: Civil Engineering solution please A wide channel has water flowing with a depth of 0.5m and the velocity on the surface is 2 m/s. • At one particular location, the boundary layer thickness, 8 = 0.2m. • Is the flow laminar or turbulent? • What is the magnitude of the displacement thickness and the momentum thickness. %3D • You may assume the following: 1/7 Velocity distribution is Uso • Density of water is 1000 kg/m³ • Absolute viscosity is 1.14 x 103 kg/(m s).
