Internal axial force diagram. Pressure is measured in psi pounds per square inch in the imperial system and kpa kilopascal or bar in the metric systemmost pressure measurements are made relative to the local atmospheric pressure. The strength of a material depends on its capacity to withstand axial stress shear stress bending and torsionthe strength of a material is measured in force per unit area newtons per square millimetre or nmm2 or the equivalent megapascals or mpa in the si system and often pounds per square inch psi in the united states customary. In that case we add a g to the pressure measurement unit such as psig or kpag. Part 1 of this two part article describes the applications performance characteristics mode and theory of operation calibration installation and maintenance procedures and the design and construction of axial turbine flowmeters.
79 animal powered chinese liberation pump mechanism uses steel components for strength to good effect see also fig. Strength depends upon material properties. Most ferrous or iron based materials are subject to corrosion problems but to compensate they are perhaps the most familiar low cost strong material that is widely available. An axial piston pump is a positive displacement pump that has a number of pistons in a circular array within a cylinder blockit can be used as a stand alone pump a hydraulic motor or an automotive air conditioning compressor.
Initially equations to evaluate leakages in all piston pump gaps will be presented and tested against numerical models later the equations will be linked to determine the general pressureflow pump dynamic characteristics.
