To avoid ambiguity, the sign of potential conforms with tbe con vention adopted by The Electrochemical Society and National Bureau of Standards. cal aspects. Theoretical treatment of tbe centrifugal pump deviates from that in existing books. Flow through the impeller is resolved into a meridional flow caused by the energy gradient drop snd a circular motion, which may mume any one of many form* of vortex motion. Many chapters, particularly those deal* ing with application* snd operation of pumps, arc practical. Therefore, even though the book was written primarily (or pump designers, consulting engineers, and plant-designing engineers, the plant op erator can use it to advantage.

ARMSTRONG 'P&cve't, tP&sC6m** STEAM TRAPS Meet All Requirements forModern High Pressure, High Temperature Service ANY engineer responsible for the design or oper/* atlon of modern high pressure, high temperature steam plants con safely provide the benefits of com pletely automatic condensate drainage by specifying Armstrong Forged Steel Steam Traps. Their inher ently trouble-free design plus highest qualitymaterials and workmanship assure safety and dependable performance. There is no chance of failure to open when condensate fills the trap and. no steam loss under no-load conditions. The extensive line includes traps to meet any pressure, temperature or capacity requirements. Armstrong Forged Steel Traps are also ideally suited to low and medium pressure service where 'all-steel" installations are desired. Where quality, safety and dependability come first, specify ARMSTRONG, the "standard" in many high pressure plants throughout the world.
