Challenge Problems

Push your limits with challenges.

Question 1

An engineer is analyzing a new pipeline with a diameter of 1 meter and a length of 800 meters. The fluid flowing through has a Reynolds number of 500,000 and a relative roughness of 0.003. Calculate the head loss using the Darcy-Weisbach equation after determining the friction factor from the Moody chart.

💡 Hint: Utilize the chart effectively and remember to reference both the equations for accurate results.

Question 2

A new formula predicts an increase in the Reynolds number from 1,000,000 to 2,000,000 for the same pipeline. Describe how this would change the friction factor based on the Moody chart and the effect on head loss.

💡 Hint: Think about the flow regimes and how they adapt between laminar and turbulent.
