Water at 15 degree C (rho = 999. 1 kg/m^3 and mu = 1.138 times 10^-3 kg/m s is flowing steadily in a long smooth pipe. The pipe diameter D is 10 cm. The flow is turbulent, and the wall shear velocity is 0.03 m/s. Determine the velocity of water at the location of y = 0.1D to the pipe surface. Water at 15 degree C (rho = 999. 1 kg/m^3 and mu = 1.138 times 10^-3 kg/m s is flowing steadily in a long pipe of 5 cm in diameter. The roughness height on the pipe surface is 2 mm. The flow is turbulent, and the wall shear velocity is 0.03 m/s. Determine whether the flow is hydraulic smooth, rough or transitional.
