This document discusses pumps and turbines as energy conversion devices. It begins by defining key terms like head, power, and efficiency as they relate to pumps and turbines. It then describes the main types of pumps and turbines, distinguishing between impulse and reaction turbines, and positive-displacement and dynamic pumps like centrifugal pumps. The document outlines how to determine the duty point by matching pump and system characteristics. It also discusses hydraulic scaling laws for relating pump performance at different speeds. Finally, it provides an overview of common pump and turbine designs and the problem of cavitation.
