SUMMARY
The discussion focuses on calculating the mean radius of a gas turbine rotor using the formula r_m = mdot / (2 * π * U * N), where r_m is the mean radius in feet, mdot is the mass flow rate in lbm/s, U is the blade velocity in ft/s, and N is the RPM. Participants emphasize the importance of correctly converting RPM to seconds and using π to convert radians. Accurate unit conversions are crucial for obtaining the correct mean radius value.
