Question 1
If a turbulent fluid has an average velocity given by the following equation, what would be the average flow rate if the diameter of the pipe is 0.5 m?
💡 Hint: Recall your area calculations and substitute into flow equations.
Question 2
Create a scenario where you must choose between a smooth or rough pipe. Analyze how this would change average velocity with sufficient details.
💡 Hint: Incorporate both scientific equations discussed and give practical examples.
