Challenge Problems
Push your limits with advanced challenges
Calculate the change in pressure loss for a rough pipe with a diameter of 0.2 m, flow rate of 0.5 m³/s, and average flow velocity using Darcy-Weisbach equation, given the Darcy friction factor based on Reynolds number is 0.02.
💡 Hint: Break down each component of the equation stepwise.
If the diameter of a pipe is reduced to half, explain how this affects the Reynolds number, and the flow's character—discuss implications.
💡 Hint: Think about how changes in cross-section affect velocity and continuity.
