Challenge Problems
Push your limits with advanced challenges
Given a pipe with a diameter of 0.1 m, a roughness height of 0.001 m, and a fluid flowing at a velocity of 2 m/s, calculate the head loss using the Darcy-Weisbach equation.
💡 Hint: You will need to know the total length of the pipe and the specific gravity of the fluid.
Analyze how increasing roughness in pipes impacts flow speed and energy loss at high Reynolds numbers.
💡 Hint: Focus on the relationship between turbulence, friction factor, and flow speed.
