I'm given a study which has given gas velocity on stator pressure side and on suction side to be 300 m/s and 400 m/s and given mach number 0.45 and 0.7. I was wondering how the gas velocity was calculated from the given mach number
Approximate concentrations are require in compared with the WHO permissible limts
