4 cards from this section. Quick, good the night before a test.
What does the Energy Grade Line (EGL) represent?
Think about the different energy forms in fluid mechanics.
How is the Hydraulic Grade Line (HGL) defined?
Consider which energies contribute to the height of the fluid in a piezometer.
What does the Energy Grade Line (EGL) indicate?
Think about how energy converts in flows.
True or False: The Hydraulic Grade Line (HGL) is always above the EGL.
Remember the relationship between EGL and HGL.
A fluid flows through a pipe that narrows at one point. Explain how and why the EGL changes as fluid speeds up due to the narrowed section.
Consider how velocity and pressure relate in a tapered pipe.
Design a simple experiment using a pitot tube to measure the airspeed of a fan. Describe how the EGL and HGL will be positioned in your setup.
Think about how pressure measurements inform energy distribution in your system.
