Description: differential pressure measured between the inlet and outlet ports for the operating conditions; Name: diff pr rated
Description: Differential pressure for the operating conditions at the guarantee point ; Name: Rated differential pressure 
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
