Compressors and pumps, often called working machines, are used to move materials for a large variety of purposes. Compressors are machines that increase the pressure of a gas through input of mechanical work. Similarities exist between the design of compressors and the design of pumps.

Flow in Transonic Compressors [PDF]
AIAA Journal, 1980 Introduction B the term transonic compressor we mean an axial flow compressor in which the inlet flow Mach number, relative to the rotating blades, varies from below unity at radii near the inner casing or hub to values substantially above unity at radii near the blade tips.

Afemoral artery compression device is described which is employed in percutaneous aortography after the needle or catheter is withdrawn. This apparatus can save about fifteen minutes of professional time per study but, of more importance, it reduces the incidence of recurrent bleeding caused by premature release of manual compression from the artery ...

Publisher Summary This chapter focuses on centrifugal compressors that are used in small gas turbines, and are the driven units in most gas turbine compressor trains. They are an integral part of the petrochemical industry, finding extensive use because of their smooth operation, large tolerance of process fluctuations, and their higher reliability ...

Publisher Summary This chapter discusses the number and size of compressor stations required to transport gas in a pipeline. The optimum locations and pressures at which compressor stations operate are determined based on the pipeline flow rate, allowable pipe operating pressures, and pipeline topography.

Journal of the American Oil Chemists' Society, 1956
ConclusionsMany new developments in pumping and compressing have recently been reported. The new equipment and theories reported will probably find frequent uses in the oil processing and chemical industries. The result will be lower pumping costs and better service.
