Consider the deductive proofs provided in the lectures.
Question 5.
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?
Show hintHide hint
Recall your area calculations and substitute into flow equations.
Question 6.
Create a scenario where you must choose between a smooth or rough pipe. Analyze how this would change average velocity with sufficient details.
