This powerpoint presentation begins by providing a brief overview of hydraulic transients. Controling hydraulic transients is outlined, along with the issue of hydraulic surges, preventing control valves from creating surges, observed and predicted surge pressures, slower opening time, modifying system configuration, created pressure waves, preventing a control valve from creating a vacuum, pipe break, predicted surge pressures, rapid demand change, pump start-up simulation, field data vs. model prediction - power failure event, system evaluation - surge control, variations, and summary of critical factors to be considered in successful transient analysis. Includes figures.
