Description: mean flow velocity through the valve opening area; Name: valve opening speed
Description: mean velocity of the flow through the valve spill area; Name: valve spill velocity
Description: minimum value of ratio between the applied shear stress and rate of shear of a liquid at concept 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: minimum dynamic viscosity at design temperature
