Question 1
A water pipe with a diameter of 0.1 m has a roughness height of 0.002 m. If the fluid has a Reynolds number of 5000, calculate the friction factor.
💡 Hint: Recall how to utilize Moody's chart, or use formulas for turbulent flow.
Question 2
Compare the energy losses of a smooth vs. a rough pipe over the same length and flow rate. Explain the implications for engineering design.
💡 Hint: Think about how different characteristics will influence the flow dynamics.
