Given a pipe of length 100 meters, diameter 0.2 meters, and an average velocity of 3 m/s, calculate the head loss using the Darcy-Weisbach equation if the friction factor is determined to be 0.02.
💡 Hint: Make sure to convert the velocity correctly in your calculations.
Explain how you would use the Moody chart to determine the friction factor for a pipe with a known roughness height of 0.003 m and a Reynolds number of 5000.
💡 Hint: Recall that the chart indicates values based on friction levels for various conditions.
