This document is an instructional module package prepared in objective form for use by an instructor familiar with the application of hydraulic principles to water supply and water pollution control systems including water distribution systems and sewer systems. Included are objectives, instructor guides, student handouts and transparency masters. This is the second level of a two module series. Presented are aspects of hydrostatics, Bernoullis equation and energy relationships for flow systems including frictional losses and pump work input, hydraulic models of flowthrough tanks; and overall hydraulic analysis of systems.
