The method of approach by "Mero-plastical Dynamics"** has been applied to estimate the shearing stress and inertia force for agitating fluidised beds. The modified "M"number, HM'', which has been derived from the force balance for agitating fluidised solid beds, is defined as follows, NM'' =NR/√gLetanφwhich is based on fluidised solid beds, radius of blade and rotational speed, and is quite similar to the Reynolds number for agitating liquids. The general correlation of the power number, Np, with HM'' for agitating fluidised beds, including the literature data, has been determined experimentally in the following equation similar to those for agitating fixed solid beds and for liquids in tanks. NP=35NM''-1+50
