Energy and Hydraulic Gradient Lines
MetadataShow full item record
This interactive tutorial reviews the variations of Energy Grade Line (EGL) and Hydraulic Grade Line (HGL) along a pipe of varying areas for a given flow rate. Explanations are illustrated by animated graphs. There is an interactive exercise in which the cross-sectional area of a pipe may be varied, so the variations in the pressure and velocity may be observed graphically.
