A turbulent flow of water in a pipe of diameter 800 mm has velocity profile as

where velocity u is in m/s and the distance y from the wall is measured in m. If shear stress at a point 0.1 m from the wall is measured as 1.25 N/m2, then find the turbulence viscosity, mixing length and turbulence constant.
