Description: rotor critical speed calculated assuming that there are no liquid effects, that the rotor is supported only at its bearings and that the bearings are of infinite stiffness; Name: dry crit. Speed
Description: Rotor resonant frequency calculated assuming that the rotor is supported only at its bearings and that the bearings are of infinite stiffness ; Name: Dry critical speed
Description: determined through a surface, product of the sound pressure, p, and the component of the particle velocity, un, at a point on the surface in the direction normal to the surface, integrated over that surface; Name: sound power
