Usually this can be relieved by running the rotor in the balance stand until the level of unbalance reaches a steady state level. Do not start balancing until steady state is achieved. Storing rotors vertically is preferred. Shipping.

    The energy yield of a cased pressure-staged turbine of this kind is about ten times greater than that of a velocity staged open-air turbine of the same diameter. Air speed before and after the turbine is about the same. The output achieved is proportional to the product of volume flow per time unit and the fall in pressure at the turbine.
