A method is presented by which the energy and continuity relations are simultaneously solved to express the velocity distributions downstream of any compressor blade row in terms of outlet total temperature, total pressure, and relative flow angle. The method is intended for use in units in which only a limited amount of experimental data can be obtained. The determination of the velocities downstream of a stationary blade row assumes that the condition of simple radial equilibrium is satisfied and that the entropy is constant along the radius.
