Water at 20°c is flowing uniformly in a wide rectangular channel at an average velocity of 1.3 m/s. if the water depth is 0.16 m, determine whether the flow is laminar or turbulent and whether the flow is subcritical or supercritical. the density and dynamic viscosity of water at 20ºc are rho = 998.0 kg/m3 and μ = 1.002 × 10–3 kg/m·s.
