An approximate method to compute mean velocity profiles in turbulent flows is developed. This approach is based on the equation connecting the Reynolds stress and mean velocity. By using the measured values of pressure drop and average (bulk) flow velocity, such characteristics of a turbulent flow as the mean velocity and Reynolds stress distributions were calculated and compared with the experimental measurements in different pipes and channels for various fluids and gases. These show good agreement for a wide range of Reynolds numbers.
