Description: index relating flow, total head and rotational speed for pumps of similar geometry; Name: specific speed
Description: Speed that characterizes a pump in terms of its speed, flow rate per impeller eye, i.e. total flow for single-flow impeller, half flow for double-flow impeller, at the best efficiency point and head per stage at maximum impeller diameter ; Name: Specific speed
Description: maximum value of ratio between the applied shear stress and rate of shear of a liquid at design temperature it is sometimes referred to as the coefficient of dynamic viscosity, or simply viscosity, thus dynamic viscosity is a measure of the resistance to flow or deformation of a liquid; Name: maximum dynamic viscosity at design temperature
