Challenge Problems
Push your limits with advanced challenges
A reservoir system has two reservoirs with a height difference of 20m. If the connecting pipe is 400m long and has a diameter of 0.15m, calculate the flow rate, considering a friction factor of 0.025 and a minor loss coefficient of 1.5.
💡 Hint: Ensure you consider both major and minor losses before deriving the flow.
For a system with a total head loss of 50m, comprising 30m major head loss and 20m minor head loss, discuss how changes in pipe diameter would affect the head loss.
💡 Hint: Revisiting the Darcy equation can clarify this relationship.
