The cascade considerations presented in Part I are extended to obtain interrelations between cascade parameters and machine similarity parameters, and to assess the effect of compressibility on these interrelations. These data are used to compute the efficiency potential and cavitation sensitivity of single cascaded and multiple cascaded axial machines in the medium to high specific speed regime. The calculated data show fair agreement with the available test information. The effect of only a limited number of design parameters has been investigated. Further studies will be required to cover the performance potential adequately.
