Mass-flow tables for ratios of specific heats of 1.3 and 1.4 are presented for the entire range of critical velocity ratio. The tables enable a quick and accurate determination of the integrated average specific mass flow across a region where the end-point velocities are known, commensurate with the assumptions that the total state is constant and the static pressure varies linearly between the two velocities. A numerical example is included to illustrate the use of the tables. All quantities are in nondimensional form and are tabulated sgainst critical velocity ratio. The tables include specific-mass-flow parameter and ratio of static to total pressure.
