    Abstract - (Show below) - (Hide below)

    Deals with terms, letter symbols and units relating to the flow of liquids through rotodynamic and positive displacement liquid pumps and positive displacement liquid pumps and associated installations. Provides a means of clarifying communications between the installation designer, operator, manufacturer and plant constructor. Identifies the units in common usage but all further legal units may be used. A definition of a liquid pump is included. Does not cover terms, letter symbols and units that refer to the component parts of rotodynamic and positive displacement pumps and installations.
