What do equipotential lines represent?
Think about water levels in piezometers.
What is the formula for head drop (∆h)?
It relates to how we divide total head.
What do equipotential lines indicate?
How do they relate to flow lines?
True or False: Water can flow along an equipotential line.
Consider the definition of hydraulic gradient.
What is the flow rate through a permeameter with a head drop of 36 m across 6 flow channels, and permeability of 3 m/s?
Ensure you divide head drop by the number of channels correctly.
A soil layer has a head drop of 25 m with permeability of 2 m/s and you divide it into 5 flow channels. Calculate the total flow.
Focus on the relationships among the variables.
