Question 5.
A horizontal pipe has varying diameters; explain how you would analyze the flow using Bernoulli's equation, considering viscosity.
Show hintHide hint
Remember to connect flow rate changes with velocity gradients in different pipe sections.
Question 6.
In a real-world scenario where water flows through a system with significant friction, develop a strategy using Bernoulli's equation to estimate the pressure drop.
Show hintHide hint
Think about how you could calculate losses in different sections of a pipe system.
