    Degree of agitation is the guide line for optimizing the rate of suspension of solids which ranges from 1 to 10. For vigorous agitation in any vessel/tank the calculated degree of agitation may work out to more than 10 but it is considered as equal to 10 only. Degree of agitation = Bulk fluid Velocity/6 For 6 ft/min Degree of agitation = 1
