S.GOLDSTEIN's analysis of propeller satisfying Betz condition is extended to case where hub radius is appreciable relative to propeller radius; solution, which satisfied boundary conditions of infinitely long cylinder representing hub, is expressed as infinite series of modified Bessel functions; differences between present case and that with zero hub radius can be calculated without too much difficulty.
