A gas mixture at a total pressure of 117kPa and 304K contains 25%H2,37%O2, and the rest H2O by volume. The absolute velocity of each species are 7,1, and 14m/s, respectively, all in the direction of the z-axis. Determine (a) the mass average velocity, (b) the molar average velocity, (d) the molar flux of O2, and (c) the mass flux of O2
