mass and its centripetal acceleration is equal to the Unbalance force. The centripetal acceleration is the product of the distance between the Shaft Axis and the Unbalance Mass and the square of the angular velocity of the Rotor in radians per second.
Normally the mass flow rate of superheated steam (live steam) is known. Thus, mass flow rate. calculations start usually by calculating the mass flow rate of spray water to the last spray water. group (which is in this example between the second and third superheater stages).

If we want to know correction mass, m c, at a radius of r, it will be given by / c e r m m = () The correction should be placed 1800 away from unbalance mass m. Such a correction is called a single plane balancing of the rotor, which eliminates the inertia forces transmitted to the foundation (or bearing).
