How do calculate gd2 value for agitator?

To calculate the GD² value for an agitator, you need to determine the mass (G) of the agitator and the square of the distance (D) from the center of rotation to the mass's center of gravity. The formula is GD² = G × D². First, measure or estimate the mass of the agitator components, then calculate the distance from the center of rotation to the center of gravity for each component, square that distance, and multiply by the mass. Sum the GD² values of all components to get the total GD² for the agitator.
