Challenge Problems
Push your limits with advanced challenges
Calculate the total energy for a channel with a uniform depth of 4 ft and velocity of 5 ft/s under gravitational acceleration of 32.2 ft/s².
💡 Hint: Plug in depth and velocity correctly into the specific energy formula.
Design a minim-sized channel with a width of 2 ft that can sustain a flow rate of 10 ft²/s and calculate its downstream conditions.
💡 Hint: Use q = A * v for flow calculations, A being width times depth.
