Challenge Problems
Push your limits with challenges.
Question 1
Given an open channel flow where the depth is 3m and velocity is 5m/s, calculate the specific energy and identify the flow regime. If the channel is designed to carry 120m³/s, what could the critical depth be?
💡 Hint: Utilize specific energy equations for calculations and consider flow discharge.
Question 2
Discuss how you would design an irrigation channel using specific energy principles to minimize energy loss while maximizing flow efficiency.
💡 Hint: Research trade-offs between depth and velocity.
